Struct ResidueScanner 

pub struct ResidueScanner {
    markers: Vec<String>,
    max_marker_len: usize,
    tail: String,
    hit: Option<String>,
}

Chunk-safe residue scanner. See the module docs.

Fields

markers: Vec<String>

Markers to scan for: the active spec’s (if any) ∪ the known set.

max_marker_len: usize

Longest marker length in bytes — bounds the retained tail.

tail: String

Tail of the previous chunk that could still open a marker.

hit: Option<String>

First marker found, if any. Sticky.

Implementations

impl ResidueScanner

pub fn new(dialect: Option<&DialectSpec>) -> Self

Build a scanner for a model with the given resolved dialect.

pub fn feed(&mut self, chunk: &str)

Scan one chunk of client-visible text.

Cheap after the first hit (immediately returns). Never alters the text — the caller forwards it regardless.

pub fn hit(&self) -> Option<&str>

The first marker seen in the fed text, if any.

fn scan(&self, window: &str) -> Option<String>

Trait Implementations

impl Debug for ResidueScanner

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
