Struct GuardedEvent 

pub struct GuardedEvent {
    pub chunk: Chunk,
    pub alias_delta: u64,
    pub start: u64,
}

One executed event of a recorded file: its compiled chunk, plus what a replay needs to know that the chunk is still the program the lexer would produce now.

A chunk is lexed text, and lexing depends on the alias tables as the earlier events left them. alias_delta is how many alias-table mutations had happened since the file began when this event was lexed; a replay that has made a different number by the time it reaches the event (a conditional alias took the other branch) is no longer running the recorded program, and carries on from start, the byte offset of the event in the file, by lexing the rest of it afresh.

Fields

chunk: Chunk

alias_delta: u64

start: u64
