Struct Cpattern 

pub struct Cpattern {
    pub next: Option<Box<Cpattern>>,
    pub tp: i32,
    pub str: Option<Vec<u8>>,
    pub chr: u32,
}

Port of struct cpattern from Src/Zle/comp.h:197-210. A single pattern element in a matcher specification — represents one character either in the trial completion or in the word on the command line.

The C union { char *str; convchar_t chr; } u is dispatched by tp (a CPAT_* constant). The Rust port keeps both fields with Options so the dispatcher reads only the live one.

Fields

next: Option<Box<Cpattern>>

Next sub-pattern.

tp: i32

Type of object — one of CPAT_*.

str: Option<Vec<u8>>

If a character class (CPAT_CCLASS/CPAT_NCLASS/CPAT_EQUIV), the objects in it as a metafied byte sequence — the encoded format matches Src/pattern.c’s patmatchindex reader: 0x80 + PP_* for POSIX classes, 0x80 + PP_RANGE + two bytes for ranges, plain bytes for literals. Storing as Vec<u8> (not String) preserves the 0x80-0xBF marker bytes that would otherwise mangle under UTF-8 validation.

chr: u32

If a single character (CPAT_CHAR), it.
