Trait StrPredicate

Source

pub trait StrPredicate<B: FallibleBool>: FnMut(&str) -> B + Sized {
    // Provided method
    fn expecting(self, len: usize) -> SizedStrPredicate<Self, B> { ... }
}

Expand description

Convert FnMut(&str) -> FalliableBool into a pattern by specifying a look-ahead length.

Provided Methods§

Source

fn expecting(self, len: usize) -> SizedStrPredicate<Self, B>

Returns a pattern by giving a length hint on a string predicate

§Note

All chars above position zero are obtained through peeking
Do not expect all incoming strings to be length len, the user is expected to handle edge cases.

§Panics

if len is 0

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
