Struct FileStyleRegistry 

pub struct FileStyleRegistry {
    pub rules: Vec<StyleRule>,
    pub callback: Option<FileStyleCallback>,
    /* private fields */
}

Registry of file styles applied in the in-UI file browser.

Rules are evaluated in insertion order. The first matching rule wins.

Fields

rules: Vec<StyleRule>

Ordered rule list.

callback: Option<FileStyleCallback>

Optional callback provider for dynamic style resolution.

Implementations

impl FileStyleRegistry

pub fn igfd_ascii_preset() -> Self

Returns a small, dependency-free style preset that resembles a classic file dialog.

This preset uses ASCII icons only (e.g. "[DIR]") to avoid relying on icon fonts. Hosts can override these rules or provide richer icons via an icon font + font_token.

pub fn invalidate_caches(&mut self)

Invalidate cached compiled regex patterns.

This is called automatically by push_* methods. If you mutate rules directly, call this before rendering.

pub fn push_rule(&mut self, matcher: StyleMatcher, style: FileStyle)

Add a rule.

pub fn push_dir_style(&mut self, style: FileStyle)

Convenience: style all directories.

pub fn push_file_style(&mut self, style: FileStyle)

Convenience: style all files.

pub fn push_link_style(&mut self, style: FileStyle)

Convenience: style all symbolic links.

pub fn push_extension_style(&mut self, ext: impl AsRef<str>, style: FileStyle)

Convenience: style a specific extension (case-insensitive, without leading dot).

pub fn push_name_style(&mut self, name: impl AsRef<str>, style: FileStyle)

Convenience: style a specific base name (case-insensitive).

pub fn push_name_contains_style( &mut self, needle: impl AsRef<str>, style: FileStyle, )

Convenience: style entries whose base name contains a substring (case-insensitive).

pub fn push_name_glob_style( &mut self, pattern: impl AsRef<str>, style: FileStyle, )

Convenience: style entries whose base name matches a glob (* / ?, case-insensitive).

pub fn push_name_regex_style( &mut self, pattern: impl AsRef<str>, style: FileStyle, )

Convenience: style entries whose base name matches a regex (case-insensitive).

IGFD-style wrappers are accepted: ((...)).

pub fn set_callback(&mut self, callback: FileStyleCallback)

Set a callback provider for dynamic style resolution.

pub fn clear_callback(&mut self)

Clear the callback provider.

pub fn style_for(&mut self, name: &str, kind: EntryKind) -> Option<&FileStyle>

Resolve a style for an entry.

pub fn style_for_owned( &mut self, name: &str, kind: EntryKind, ) -> Option<FileStyle>

Resolve style as an owned value, checking callback first then static rules.
