Crate ferriki 

Reusable, synchronous Ferriki highlighter for Rust applications.

The library has no Node.js or N-API dependency. Asset catalogs are loaded explicitly and cached for reuse across code blocks and documents.

Structs

AssetDigest

A normalized SHA-256 digest; safe to use as a cache filename.

AssetMetadata

Release-pinned integrity information for one payload.

BacktrackingWarning

An advisory finding from a regex scanner that Ferriki has compiled.

DirectoryAssetSource

Reads a digest-addressed directory, such as a pre-populated offline cache.

EmbeddedAssetSource

Borrowed or owned offline payloads, deduplicated by digest.

Error

An owned error with a stable category and human-readable context.

FontStyle

TextMate font style bits. Serializes as its integer value; NOT_SET is -1.

HighlightThemeMetadata

Resolved metadata for a requested theme variant.

HighlightThemeToken

A source segment aligned across all requested themes.

HighlightThemeTokenStyle

Owned style for one named theme variant of a token.

HighlightToken

HighlightTokensResult

HighlightTokensWithThemesResult

Owned tokens and theme metadata for multi-theme highlighting.

HighlightedLines

Escaped, balanced inner HTML and the theme colors for one code block.

Highlighter

Reusable, synchronous highlighter for Rust consumers.

HighlighterBuilder

Configuration for a reusable highlighter.

HtmlWithCss

Class-based HTML and the stylesheet required by its resolved theme.

LanguageRegistration

A typed custom TextMate grammar registration.

RawGrammar

RawTheme

RawThemeSetting

RawThemeStyle

ReleaseAsset

One pinned payload of a ReleaseManifest.

ReleaseManifest

Digest, size and format version of every grammar, bytecode and theme payload.

RenderOptions

StandardAssetCatalogs

ThemeData

TokenizeOptions

Enums

BacktrackingRisk

The pattern shape Ferroni identified as a possible source of excessive backtracking.

ErrorKind

Stable category of a Rust highlighter failure.

ParseRawGrammarError

RawThemeScope

StandardTokenType

The standard token type of vscode-textmate. Serializes as its numeric value.

StyleMode

Controls how theme styles are emitted.

Traits

AssetSource

Supplies immutable asset bytes by digest. Sources may perform synchronous I/O while explicitly loading assets; they must not implement retries here. Catalogs verify returned bytes before decoding or retaining them.

Functions

parse_raw_grammar

Parse a TextMate grammar, selecting JSON only for .json file names.

parse_theme_data

render_hast

Renders a HAST tree, with styles extracted to classes when requested.

render_html

render_html_lines

Renders trusted, tag-balanced HTML fragments for each highlighted line.

render_html_with_css

Renders class-based HTML with CSS for this block. Combine CSS from every block. Existing TextMate themes are resolved during tokenization and need no conversion.

Type Aliases

Result

Result returned by the native Ferriki runtime.
