Trait rdiff::string_diff::OperationScore [−] [src]

pub trait OperationScore {
    fn insert_score(&self, c: char) -> i32;
    fn delete_score(&self, c: char) -> i32;
    fn substitution_score(&self, old: char, new: char) -> i32;
    fn match_score(&self, c: char) -> i32;
}

Used to calculate the score for each operation that will be performed. The score can be static, or it can vary based on which character is being deleted inserted or substituted. It is highly recommended to inline the implementation of these characters

Required Methods

fn insert_score(&self, c: char) -> i32

The score for inserting character c into the string

fn delete_score(&self, c: char) -> i32

The score for deleting character c from the string

fn substitution_score(&self, old: char, new: char) -> i32

The score for replacing character old with character new

fn match_score(&self, c: char) -> i32

The score for when a character is one string matches the character in the other string
