Struct Hunk

pub struct Hunk {
    pub before: Range<u32>,
    pub after: Range<u32>,
}

A single change in a Diff that represents a range of tokens (before) in the first sequence that were replaced by a diffrerent range of tokens in the second sequence (after).

Tokens that are a

Fields

before: Range<u32>

after: Range<u32>

Implementations

impl Hunk

pub const NONE: Hunk

Can be used instead of Option::None for better performance. Because imara-diff does not support more then i32::MAX there is an unused bit pattern that can be used. Has some nice properties where it usually is not necessary to check for None seperatly: Empty ranges fail contains checks and also faills smaller then checks.

pub fn invert(&self) -> Hunk

Inverts a hunk so that it represents a change that would undo this hunk.

pub fn is_pure_insertion(&self) -> bool

Returns whether tokens are only inserted and not removed in this hunk.

pub fn is_pure_removal(&self) -> bool

Returns whether tokens are only removed and not remved in this hunk.

Trait Implementations

impl Clone for Hunk

fn clone(&self) -> Hunk

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Hunk

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Hunk

fn default() -> Hunk

Returns the “default value” for a type.

impl Hash for Hunk

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Hunk

fn eq(&self, other: &Hunk) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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