+example.cpp has the code i use to write out evtc files.
+check file header for environment: evtc bytes for filetype, arcdps build yyyymmdd for compatibility, target species id for boss/manual.
+create agents and skills table from evtc, consider dynamic expansion - some nameless/combatless agents may not be written.
+skill and agent names use utf8 encoding.
+evtc_agent.name is a combo string on players - character name <null> account name <null> subgroup str literal <null>.
+add u16 field to the agent table, agents[x].instance_id, initialized to 0.
+add u64 fields agents[x].first_aware initialized to 0, and agents[x].last_aware initialized to u64max.
+add u64 field agents[x].master_addr, initialized to 0.
+if evtc_agent.is_elite == 0xffffffff && upper half of evtc_agent.prof == 0xffff, agent is a gadget with pseudo id as lower half of evtc_agent.prof (volatile id).
+if evtc_agent.is_elite == 0xffffffff && upper half of evtc_agent.prof != 0xffff, agent is a character with species id as lower half of evtc_agent.prof (reliable id).
+if evtc_agent.is_elite != 0xffffffff, agent is a player with profession as evtc_agent.prof and elite spec as evtc_agent.is_elite.
+gadgets do not have true ids and are generated through a combination of gadget parameters - they may collide with characters and should be treated separately.
+iterate through all events, assigning instance ids and first/last aware ticks.
+set agents[x].instance_id = cbtevent.src_instid where agents[x].addr == cbtevent.src_agent && !cbtevent.is_statechange.
+set agents[x].first_aware = cbtevent.time on first event, then all consecutive event times to agents[x].last_aware.
+iterate through all events again, this time assigning master agent.
+set agents[z].master_agent on encountering cbtevent.src_master_instid != 0.
+agents[z].master_addr = agents[x].addr where agents[x].instance_id == cbtevent.src_master_instid && agent[x].first_aware < cbtevent.time < last_aware.
+iterate through all events one last time, this time parsing for the data you want.
+cbtevent.src_agent and cbtevent.dst_agent should be used to associate event data with local data.
+parse event type order should check cbtevent.is_statechange > cbtevent.is_activation > cbtevent.is_buffremove.
+cbtevent.is_statechange will do the heavy lifting of non-internal and parser-requested events - make sure to ignore unknown statechange types.
+if you would like to see an event not obtainable through my cbtevent struct, let me know.
+on cbtevent.is_activation == cancel_fire or cancel_cancel, value will be the ms duration of the time spent in animation.
+on cbtevent.is_activation == normal or quickness, value will be the ms duration of the expected animation time.
+on cbtevent.is_buffremove, value will be the total duration removed of the stack/s, buff_dmg will be the duration of the longest stack.
+if they are all 0, it will be a buff application (!cbtevent.is_buffremove && cbtevent.is_buff) or physical hit (!cbtevent.is_buff).
+on physical, cbtevent.value will be the damage done (negative = healing, if ever added).
+on physical, cbtevent.result will be the result of the attack.
+on buff && !cbtevent.buff_dmg && cbtevent.value, cbtevent.value will be the millisecond duration applied. cbtevent.overstack will be apx overstack in ms.
+on buff && !cbtevent.buff_dmg && !cbtevent.value, it is negated condition damage via invuln or resistance.
+on buff && cbtevent.buff_dmg && !cbtevent.value, cbtevent.buff_dmg will be the approximate damage done on tick (negative = healing, if ever added).

+//! This module contains functions to parse an EVTC file.
+//!
+//! # Layout
+//!
+//! The general layout of the EVTC file is as follows:
+//!
+//! ```raw
+//! magic number: b'EVTC'
+//! arcdps build: yyyymmdd
+//! nullbyte
+//! encounter id
+//! nullbyte
+//! agent count
+//! agents
+//! skill count
+//! skills
+//! events
+//! ```
+//!
+//! (refer to
+//! [example.cpp](https://www.deltaconnected.com/arcdps/evtc/example.cpp) for
+//! the exact data types).
+//!
+//! The parsing functions mirror the layout of the file and allow you to parse
+//! single parts of the data (as long as your file cursor is at the right
+//! position).
+//!
+//! All numbers are stored as little endian.
+//!
+//! arcdps stores the structs by just byte-dumping them. This means that you
+//! have to be careful of the padding. `parse_agent` reads 96 bytes, even though
+//! the struct definition only has 92.
+//!
+//! # Error handling
+//!
+//! Errors are wrapped in [`ParseError`](enum.ParseError.html). I/O errors are
+//! wrapped as `ParseError::Io`. `EOF` is silently swallowed while reading the
+//! events, as we expect the events to just go until the end of the file.
+//!
+//! Compared to the "original" enum definitions, we also add
