Struct TreMatchOpts 

pub struct TreMatchOpts {
    pub max_errors: u16,
    pub cost_ins: u16,
    pub cost_del: u16,
    pub cost_subst: u16,
    pub max_cost: u16,
    pub case_insensitive: bool,
}

Per-pattern matching configuration.

max_errors is the headline knob: it bounds the number of edit operations tolerated in a match. cost_* weight each edit kind; if all weights are 1 the cost equals the edit distance. max_cost bounds the cumulative cost; setting it to 0 with max_errors > 0 is rejected because it forces exact match no matter what edits are allowed.

case_insensitive toggles TRE’s REG_ICASE flag.

Fields

max_errors: u16

Maximum number of edit operations (insert + delete + substitute) permitted in a match.

cost_ins: u16

Cost of inserting one byte. Defaults to 1.

cost_del: u16

Cost of deleting one byte. Defaults to 1.

cost_subst: u16

Cost of substituting one byte. Defaults to 1.

max_cost: u16

Cumulative cost ceiling. Zero means “use max_errors * max(cost_*) as the implicit ceiling”.

case_insensitive: bool

Match case-insensitively.
