Enum ReplaceCount 

#[non_exhaustive]
pub enum ReplaceCount {
    All,
    FirstPerLine,
    FirstInFile,
    Max(usize),
}

How many occurrences a Replace operation substitutes.

Wire format (externally tagged): unit variants serialize as plain strings ("all", "first_per_line", "first_in_file"), the capped variant as an object ({"max": 3}, counting occurrences per file).

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

All

Replace every occurrence (sed s///g, the default).

FirstPerLine

Replace only the first occurrence on each matching line (sed s///).

FirstInFile

Replace only the first occurrence in the file, then stop.

Max(usize)

Replace at most N occurrences in the file, then stop.

Trait Implementations

impl Clone for ReplaceCount

fn clone(&self) -> ReplaceCount

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ReplaceCount

impl Debug for ReplaceCount

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

Formats the value using the given formatter.

impl Default for ReplaceCount

fn default() -> ReplaceCount

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ReplaceCount

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for ReplaceCount

impl PartialEq for ReplaceCount

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
