Module params 

Lazy parser for CSI and DCS parameter bodies.

Category

Params and Group expose the bytes between a control-sequence introducer and its final byte. They handle semicolon-separated parameters and colon-separated subparameters without allocating.

Parameter grammar

A body such as 38:2::255:100:50;1 is viewed as two top-level groups. Empty slots decode to None; numeric slots decode to Some(value).

38:2::255:100:50  ;  1
─────────┬────────   ┬
     group 0       group 1

Mode interaction

Parameter defaults are sequence-specific. Callers apply defaults with Params::get_or after they know which CSI/DCS final byte and mode context they are handling.

Structs

Group

One ;-separated group within a Params body. Wraps the raw bytes for that group (no separator); decodes its colon-separated sub-parameters on demand.

ParamIter

Iterator over the ;-separated groups of a Params.

Params

Borrowed view of a CSI / DCS parameter body.

SubIter

Iterator over the :-separated sub-parameters of a Group.
