Trait Matcher 

pub trait Matcher {
    type Match<'a>;

    // Required method
    fn try_match<'a>(array: &'a dyn DynArray) -> Option<Self::Match<'a>>;

    // Provided method
    fn matches(array: &dyn DynArray) -> bool { ... }
}

Trait for matching array types.

Required Associated Types

type Match<'a>

Required Methods

fn try_match<'a>(array: &'a dyn DynArray) -> Option<Self::Match<'a>>

Try to match the given array, returning the matched view type if successful.

Provided Methods

fn matches(array: &dyn DynArray) -> bool

Check if the given array matches this matcher type

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.
