Struct PatternMapping 

pub struct PatternMapping {
    pub glob: String,
    pub destination: Option<String>,
}

A parsed pattern entry with an optional destination prefix.

The raw config value uses the syntax <glob> or <glob>:<destination>. For example:

• src/** – match src/**, no remapping (files keep their upstream path)
• src/**:ext/ – match src/**, strip the literal prefix src/, then prepend ext/ to get the local path.

Fields

glob: String

The glob string (left of the colon, or the whole value when no colon).

destination: Option<String>

The local destination prefix (right of the colon), if present.

Implementations

impl PatternMapping

pub fn parse(raw: &str) -> Self

Parse a raw pattern string, splitting on the first : only.

pub fn to_raw(&self) -> String

Serialize back to the raw config string.

pub fn literal_prefix(&self) -> &str

Extract the literal (non-glob) leading path component(s) from the glob.

“Literal prefix” is everything before the first glob character (*, ?, [). For src/**/*.rs this returns src/. For ** it returns "".

pub fn local_path(&self, upstream_path: &str) -> Option<String>

Compute the local path for an upstream file that matched this pattern.

1. Strip the literal prefix from upstream_path.
2. If a destination is set, prepend it.

Returns None if the upstream path doesn’t start with the literal prefix (which shouldn’t happen when the glob matched, but we guard defensively).

Trait Implementations

impl Clone for PatternMapping

fn clone(&self) -> PatternMapping

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PatternMapping

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

Formats the value using the given formatter.

impl PartialEq for PatternMapping

fn eq(&self, other: &PatternMapping) -> 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.
