Struct FileFilter 

pub struct FileFilter {
    pub name: String,
    pub extensions: Vec<String>,
}

File filter (e.g., “Images” -> [“png”, “jpg”]).

Extensions are matched case-insensitively and should be provided without a leading dot. Multi-layer extensions are supported by including dots in the extension string (e.g. "vcxproj.filters").

Advanced patterns (ImGui backend only):

• Wildcards: tokens containing * or ? are treated like IGFD’s asterisk filters and matched against the full extension string (e.g. ".vcx.*", ".*.filters", "*.*").
• Regex: tokens wrapped in (( … )) are treated as regular expressions and matched against the full base name (case-insensitive).

The variants created from tuples will be normalized to lowercase automatically.

Fields

name: String

Filter display name

extensions: Vec<String>

Lower-case extensions without dot (e.g., “png”, “vcxproj.filters”)

Implementations

impl FileFilter

pub fn new(name: impl Into<String>, exts: impl Into<Vec<String>>) -> Self

Create a filter from a name and extensions.

Extensions should be provided without leading dots (e.g. "png", "vcxproj.filters"). Matching is case-insensitive.

pub fn parse_igfd(spec: &str) -> Result<Vec<FileFilter>, IgfdFilterParseError>

Parse an ImGuiFileDialog (IGFD) style filter spec into one or more FileFilters.

Supported forms:

• Simple list: ".cpp,.h,.hpp"
• Collections: "C/C++{.c,.cpp,.h},Rust{.rs}"

Notes:

• Commas inside parentheses (...) do not split (IGFD rule 2).
• Regex tokens ((...)) are preserved verbatim.
• Whitespace around commas/tokens is ignored.
