impl Parse for Const

source§

fn parse(input: &ParseBuffer<'_>) -> Result<Const, Error>

source§

impl PartialEq for Const

source§

fn eq(&self, _other: &Const) -> bool

1.0.0 · source§

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

fn byte_range(&self, source: &str) -> Range<usize>

TODO(H2CO3): a faster, less naive implementation would be great. We should use the byte offset of start to compute that of end, sparing the double scan of the source up until the start location.
