Enum ContextMode 

pub enum ContextMode {
    Symmetric(usize),
    Asymmetric {
        before: usize,
        after: usize,
    },
    All,
}

Context mode for result expansion.

Represents how much surrounding context to include when retrieving content matches.

Variants

Symmetric(usize)

Symmetric context (same number of lines before and after).

Asymmetric

Asymmetric context (different lines before and after).

Fields

before: usize

Lines of context before the match.

after: usize

Lines of context after the match.

All

Full section/block expansion.

Implementations

impl ContextMode

pub const fn lines(&self) -> Option<(usize, usize)>

Get the before and after context line counts.

Returns (before, after) tuple. For All mode, returns None.

pub const fn is_all(&self) -> bool

Check if this is the All (full section) mode.

pub fn merge(self, other: Self) -> Self

Merge two context modes, taking the maximum value for each direction.

Trait Implementations

impl Clone for ContextMode

fn clone(&self) -> ContextMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ContextMode

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ContextMode

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ContextMode

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

Formats the value using the given formatter.

impl FromStr for ContextMode

type Err = String

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl PartialEq for ContextMode

fn eq(&self, other: &ContextMode) -> 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 ContextMode

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 ContextMode
