Struct Position 

pub struct Position {
    pub offset: u32,
}

Byte offset into the input where an event was emitted or an error fired.

Position used to carry (offset, line, column) (16 bytes), which pushed Result<Option<Event>, Error> to 24 bytes — too big to return in two GP registers, forcing every next_event call to spill through stack memory. Now it’s just an offset (4 bytes); line and column are reconstructed on demand by Position::resolve(input), which scans input[..offset] for newlines. The scan only fires at error sites or when the consumer explicitly asks for them.

Fields

offset: u32

Implementations

impl Position

pub const START: Self

pub const fn new(offset: u32) -> Self

pub fn resolve(&self, input: &[u8]) -> LineColumn

Compute 1-based line and column by scanning the input up to this position. O(offset) — only call when actually rendering an error.
