Struct MimeDB

pub struct MimeDB { /* private fields */ }

Hold MIME data and facilitate file type guessing.

Implementations

impl MimeDB

pub fn add_records(&mut self, records: Vec<MimeTypeRecord>)

pub fn add_shared_mime_info(&mut self, info: SharedMimeInfo)

impl MimeDB

pub fn query(&self, query: &FileQuery<'_>) -> Result<Answer<'_>, QueryError>

Query the MIME database.

pub fn query_meta(&self, meta: &Metadata) -> Answer<'_>

Use metadata to detect file types.

This function can only detect the inode/ types and application/octet-stream.

pub fn query_filename<S>(&self, name: S) -> Answer<'_>

where S: AsRef<OsStr>,

Look up MIME type information based only on a filename.

impl MimeDB

pub fn new() -> MimeDB

construct a new, empty MIME database.

pub fn type_count(&self) -> usize

Get the number of known types.

pub fn glob_count(&self) -> usize

Get the number of globs.

pub fn is_subtype(&self, typ: &str, sup: &str) -> bool

Query whether one type is a subtype of another.

pub fn description(&self, typ: &str) -> Option<&str>

Get the description of a string.

pub fn aliases(&self, typ: &str) -> Vec<&str>

Get the aliases of a type.

pub fn parents(&self, typ: &str) -> Vec<&str>

Get the parents of a type.

pub fn supertypes(&self, typ: &str) -> Vec<CachedString>

Get all known supertypes of the specified type (including itself).

Types are in discovery order, so closer supertypes are at the beginning of the list.

pub fn compare_types(&self, a: &str, b: &str) -> Ordering

Order two types, where a type is less than its supertypes
