    Truncate(usize),
    Upper,
    Lower,
    Title,
    IconMap(HashMap<String, String>),
    Prefix(String),
    Suffix(String),
    Basename,
    Dirname,

}

Format modifiers that transform variable values.

Variants

Truncate(usize)

Truncate to N characters with ellipsis.

Upper

Convert to uppercase.

Lower

Convert to lowercase.

Title

Convert to title case (capitalize first letter of each word).

IconMap(HashMap<String, String>)

Map values to icons using a lookup table. Example: {status|icon:ok=✓,warn=⚠,fail=✗}

Prefix(String)

Add a prefix to the value.

Suffix(String)

Add a suffix to the value.

Basename

Get the final component of a path (file or directory name). Example: /home/user/project → project

Dirname

Get the parent directory path. Example: /home/user/project → /home/user

Extension

Get the file extension without the leading dot. Example: main.rs → rs

Stem

Get the file name without the extension. Example: main.rs → main

Parent(usize)

Get an ancestor directory at a specific depth. Depth 1 = parent, depth 2 = grandparent, etc. Returns the basename of the ancestor. Example: /home/user/project/src with depth 2 → user

Trait Implementations

impl Clone for Modifier

fn clone(&self) -> Modifier

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Modifier

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

Formats the value using the given formatter.

impl PartialEq for Modifier

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