    pub old_count: usize,
    pub new_start: usize,
    pub new_count: usize,
    pub lines: Vec<HunkLine>,
}

A hunk in a unified diff

Fields

old_start: usize

Starting line in original file

old_count: usize

Number of lines in original file

Starting line in new file

new_count: usize

Number of lines in new file

lines: Vec<HunkLine>

Implementations

impl Hunk

pub fn new( old_start: usize, old_count: usize, new_start: usize, new_count: usize, ) -> Self

Creates a new hunk

Arguments

• old_start - Starting line in original file
• old_count - Number of lines in original file
• new_start - Starting line in new file
• new_count - Number of lines in new file

Returns

A new Hunk with empty lines

Examples

use rust_diff_analyzer::git::Hunk;

let hunk = Hunk::new(10, 5, 10, 7);
assert_eq!(hunk.old_start, 10);
assert!(hunk.lines.is_empty());

pub fn added_count(&self) -> usize

Returns count of added lines

Returns

Number of added lines in hunk

Examples

use rust_diff_analyzer::git::{Hunk, HunkLine};

let mut hunk = Hunk::new(1, 1, 1, 2);
hunk.lines.push(HunkLine::added(1, "new line".to_string()));
assert_eq!(hunk.added_count(), 1);

pub fn removed_count(&self) -> usize

Returns count of removed lines

Returns

Number of removed lines in hunk

Examples

use rust_diff_analyzer::git::{Hunk, HunkLine};

let mut hunk = Hunk::new(1, 2, 1, 1);
hunk.lines
    .push(HunkLine::removed(1, "old line".to_string()));
assert_eq!(hunk.removed_count(), 1);

pub fn added_lines(&self) -> Vec<usize>

Returns all added line numbers in new file

Returns

Vector of line numbers that were added

Examples

use rust_diff_analyzer::git::{Hunk, HunkLine};

let mut hunk = Hunk::new(1, 1, 1, 2);
hunk.lines.push(HunkLine::added(5, "new".to_string()));
hunk.lines.push(HunkLine::added(6, "lines".to_string()));
assert_eq!(hunk.added_lines(), vec![5, 6]);

pub fn removed_lines(&self) -> Vec<usize>

Returns all removed line numbers in old file

Returns

Vector of line numbers that were removed

Examples

use rust_diff_analyzer::git::{Hunk, HunkLine};

let mut hunk = Hunk::new(1, 2, 1, 1);
hunk.lines.push(HunkLine::removed(3, "old".to_string()));
assert_eq!(hunk.removed_lines(), vec![3]);

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<'de> Deserialize<'de> for Hunk

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

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.

impl Serialize for Hunk

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Hunk
