Struct RepositoryMimeDetector 

pub struct RepositoryMimeDetector<'a> { /* private fields */ }

MIME detector backed by a MimeRepository.

Implementations

impl RepositoryMimeDetector<'static>

pub fn new() -> MimeResult<Self>

Creates a detector using the embedded freedesktop MIME repository.

Returns

A repository-backed detector.

Errors

The embedded database is parsed from crate resources and is expected to be valid; this method keeps a Result return type for API consistency.

pub fn from_mime_config(config: MimeConfig) -> Self

Creates a detector using the embedded repository and explicit config.

Parameters

• config: MIME detector configuration.

Returns

A repository-backed detector.

impl<'a> RepositoryMimeDetector<'a>

pub fn with_repository(repository: &'a MimeRepository) -> Self

Creates a detector using an explicit repository.

Parameters

• repository: Repository used for all detections.

Returns

A detector borrowing repository.

pub fn with_repository_and_config( repository: &'a MimeRepository, config: MimeConfig, ) -> Self

Creates a detector using an explicit repository and config.

Parameters

• repository: Repository used for all detections.
• config: MIME detector configuration.

Returns

A detector borrowing repository.

pub fn core(&self) -> &MimeDetectorCore

Gets the shared detector core.

Returns

Shared detector core.

pub fn core_mut(&mut self) -> &mut MimeDetectorCore

Gets mutable shared detector core.

Returns

Mutable shared detector core.

pub fn repository(&self) -> &'a MimeRepository

Gets the underlying repository.

Returns

Repository used by this detector.

pub fn detect_by_filename(&self, filename: &str) -> Option<String>

Detects a MIME type from a filename.

Parameters

• filename: Path or basename to inspect.

Returns

First MIME type matched by filename, or None.

pub fn detect_by_content(&self, bytes: &[u8]) -> Option<String>

Detects a MIME type from content bytes.

Parameters

• bytes: Content prefix to inspect.

Returns

First MIME type matched by magic, or None.

pub fn detect_bytes( &self, bytes: &[u8], filename: Option<&str>, policy: MimeDetectionPolicy, ) -> Option<String>

Detects a MIME type from content bytes and an optional filename.

Parameters

• bytes: Content prefix to inspect.
• filename: Optional path or basename used for glob detection.
• policy: Strategy for resolving filename and content results.

Returns

Selected MIME type name, or None.

pub fn detect_reader( &self, reader: &mut dyn ReadSeek, filename: Option<&str>, policy: MimeDetectionPolicy, ) -> MimeResult<Option<String>>

Detects a MIME type from a seekable reader without consuming its position.

Parameters

• reader: Reader to inspect. The original stream position is restored.
• filename: Optional path or basename used for glob detection.
• policy: Strategy for resolving filename and content results.

Returns

Selected MIME type name, or None.

Errors

Returns MimeError::Io when reading or seeking fails.

pub fn detect_file( &self, file: &Path, policy: MimeDetectionPolicy, ) -> MimeResult<Option<String>>

Detects a MIME type from a local file.

Parameters

• file: Local file path to open.
• policy: Strategy for resolving filename and content results.

Returns

Selected MIME type name, or None.

Errors

Returns MimeError::Io when the file cannot be opened or read.

pub fn guess_from_filename(&self, filename: &str) -> Vec<String>

Guesses MIME type names from filename rules.

Parameters

• filename: Filename or path.

Returns

Candidate MIME type names.

pub fn guess_from_content(&self, bytes: &[u8]) -> Vec<String>

Guesses MIME type names from content magic rules.

Parameters

• bytes: Content bytes to inspect.

Returns

Candidate MIME type names.
