source · pub struct Nag(pub u8);
Expand description
A numeric annotation glyph like ?
, !!
or $42
.
Tuple Fields
0: u8
Implementations
sourceimpl Nag
impl Nag
sourcepub fn from_ascii(s: &[u8]) -> Result<Nag, InvalidNag>
pub fn from_ascii(s: &[u8]) -> Result<Nag, InvalidNag>
Tries to parse a NAG from ASCII.
Examples
use pgn_reader::Nag;
assert_eq!(Nag::from_ascii(b"??"), Ok(Nag(4)));
assert_eq!(Nag::from_ascii(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
).
