Struct ShrinkOptions 

pub struct ShrinkOptions {
    pub max_len: usize,
    pub strategy: Strategy,
    pub path_style: Option<PathStyle>,
    pub ellipsis: String,
    pub dir_length: usize,
    pub full_length_dirs: usize,
    pub mapped_locations: Vec<(String, String)>,
    pub anchors: Vec<String>,
}

Configuration for path shortening.

Fields

max_len: usize

Target maximum length. The output will be at most this long, unless the filename itself exceeds it (filenames are never truncated).

strategy: Strategy

Shortening strategy.

path_style: Option<PathStyle>

Force a specific path style instead of auto-detecting.

ellipsis: String

Custom ellipsis string. Default: "...".

dir_length: usize

Number of characters to keep per abbreviated directory segment. Default: 1.

full_length_dirs: usize

Number of trailing directory segments to keep unabbreviated. Default: 0.

mapped_locations: Vec<(String, String)>

Custom path prefix substitutions applied before shortening. Each tuple is (from, to): if the path starts with from, replace it with to. Sorted by longest match first at application time.

anchors: Vec<String>

Segment names that should never be abbreviated, regardless of strategy.

Implementations

impl ShrinkOptions

pub fn new(max_len: usize) -> Self

Create options with sensible defaults: Hybrid strategy, max_len as specified.

pub fn strategy(self, s: Strategy) -> Self

Set the shortening strategy.

pub fn path_style(self, s: PathStyle) -> Self

Force a specific path style.

pub fn ellipsis(self, e: impl Into<String>) -> Self

Set a custom ellipsis string.

pub fn dir_length(self, n: usize) -> Self

Set the number of characters to keep per abbreviated directory segment.

pub fn full_length_dirs(self, n: usize) -> Self

Set the number of trailing directory segments to keep unabbreviated.

pub fn map_location( self, from: impl Into<String>, to: impl Into<String>, ) -> Self

Add a mapped location: if the path starts with from, replace it with to.

pub fn anchor(self, name: impl Into<String>) -> Self

Add an anchor segment name that should never be abbreviated.
