Enum ParseStatus 

Source 
#[repr(i32)]
pub enum ParseStatus {
    PARSE_NULL = 0,
    PARSE_OK = 1,
    PARSE_INCOMPLETE = 2,
    PARSE_ERROR = 3,
    PARSE_EOF = 4,
}
Expand description

Outcome of R_ParseVector (from R_ext/Parse.h).

PARSE_NULL is never returned by R_ParseVector; the meaningful success value is ParseStatus::PARSE_OK. The remaining variants indicate parse failures (PARSE_ERROR), incomplete input (PARSE_INCOMPLETE), or end-of-input (PARSE_EOF).

Variants§

§

PARSE_NULL = 0

Never returned by R_ParseVector; the default-initialized sentinel.

§

PARSE_OK = 1

Parse succeeded.

§

PARSE_INCOMPLETE = 2

Input ended mid-expression (e.g. an unbalanced delimiter).

§

PARSE_ERROR = 3

A syntax error was encountered.

§

PARSE_EOF = 4

End of input reached with no further expressions.
