Struct HunkHeader

pub struct HunkHeader {
    pub old_line_no: u32,
    pub old_size: u32,
    pub new_line_no: u32,
    pub new_size: u32,
    pub text: Vec<u8>,
}

Meta data which precedes a Hunks content.

For example: @@ -24,8 +24,6 @@ use radicle_surf::diff::*;

Fields

old_line_no: u32

Line the hunk started in the old file.

old_size: u32

Number of removed and context lines.

new_line_no: u32

Line the hunk started in the new file.

new_size: u32

Number of added and context lines.

text: Vec<u8>

Trailing text for the Hunk Header.

From Git’s documentation “Hunk headers mention the name of the function to which the hunk applies. See “Defining a custom hunk-header” in gitattributes for details of how to tailor to this to specific languages.“. It is likely best to leave this empty when generating diffs.

Implementations

impl HunkHeader

pub fn old_line_range(&self) -> Range<u32>

pub fn new_line_range(&self) -> Range<u32>

Trait Implementations

impl Clone for HunkHeader

fn clone(&self) -> HunkHeader

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HunkHeader

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

Formats the value using the given formatter.

impl Decode for HunkHeader

fn decode(r: &mut impl BufRead) -> Result<Self, Error>

Decode, and fail if we reach the end of the stream.

fn try_decode(r: &mut impl BufRead) -> Result<Option<Self>, Error>

Decode, and return a None if we reached the end of the stream.

fn parse(s: &str) -> Result<Self, Error>

Decode from a string input.

fn from_bytes(bytes: &[u8]) -> Result<Self, Error>

Decode from a string input.

impl Default for HunkHeader

fn default() -> HunkHeader

Returns the “default value” for a type.

impl Encode for HunkHeader

fn encode(&self, w: &mut Writer<'_>) -> Result<(), Error>

Encode type into diff writer.

fn to_unified_string(&self) -> Result<String, Error>

Encode into unified diff string.

impl PartialEq for HunkHeader

fn eq(&self, other: &HunkHeader) -> 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 ToPretty for HunkHeader

type Output = Line

The output of the render process.

type Context = ()

Context that can be passed down from parent objects during rendering.

fn pretty<R: Repo>( &self, _hi: &mut Highlighter, _context: &Self::Context, _repo: &R, ) -> Self::Output

Render to pretty diff output.

impl TryFrom<&Hunk<Modification>> for HunkHeader

type Error = Error

The type returned in the event of a conversion error.

fn try_from(hunk: &Hunk<Modification>) -> Result<Self, Self::Error>

Performs the conversion.
