)
Char(char)
A character literal ('a'
)
Int(u128, LitIntType)
An integer literal (1
)
Float(Symbol, FloatTy)
A float literal (1f64
or 1E10f64
)
FloatUnsuffixed(Symbol)
A float literal without a suffix (1.0 or 1.0E10
)
Bool(bool)
A boolean literal
Methods
impl LitKind
[src]
pub fn is_str(&self) -> bool
[src]
Returns true if this literal is a string and false otherwise.
pub fn is_unsuffixed(&self) -> bool
[src]
Returns true if this literal has no suffix. Note: this will return true for literals with prefixes such as raw strings and byte strings.
pub fn is_suffixed(&self) -> bool
[src]
Returns true if this literal has a suffix.
