Trait MergableSpan 

pub trait MergableSpan: Clone {
    // Required methods
    fn can_append(&self, other: &Self) -> bool;
    fn append(&mut self, other: Self);

    // Provided method
    fn prepend(&mut self, other: Self) { ... }
}

Required Methods

fn can_append(&self, other: &Self) -> bool

See if the other item can be appended to self. can_append will always be called immediately before append.

fn append(&mut self, other: Self)

Merge the passed item into self. Essentially, self = self + other.

The other item must be a valid target for merging (as per can_append(), above).

Provided Methods

fn prepend(&mut self, other: Self)

Append an item at the start of this item. self = other + self.

This item must be a valid append target for other. That is, other.can_append(self) must be true for this method to be called.

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.
