Struct pgn_reader::Nag
[−]
[src]
pub struct Nag(pub u8);
A numeric annotation glyph like ?
, !!
or $42
.
Methods
impl Nag
[src]
fn from_bytes(s: &[u8]) -> Result<Nag, InvalidNag>
[src]
Tries to parse a NAG from ASCII.
Examples
use pgn_reader::Nag; assert_eq!(Nag::from_bytes(b"??"), Ok(Nag(4))); assert_eq!(Nag::from_bytes(b"$24"), Ok(Nag(24)));
Errors
Returns an InvalidNag
error if the input is neither a known glyph
(?!
, !
, ...) nor a valid numeric annotation ($0
, ..., $255
).
