Methods

impl LitKind

pub fn is_str(&self) -> bool

Returns true if this literal is a string and false otherwise.

pub fn is_unsuffixed(&self) -> bool

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

Returns true if this literal has a suffix.
