pub fn import_formats() -> Vec<Self>

Returns all available formats for import.

pub fn export_formats() -> Vec<Self>

Returns all available formats for export.

pub const fn extension(&self) -> &'static str

Returns the file extension for this format.

pub const fn mime_type(&self) -> &'static str

Returns the MIME type for this format.

pub fn from_path(path: &Path) -> Result<Self>

Detects format from file extension.

Errors

Returns an error if the extension is not recognized.

pub const fn supports_import(&self) -> bool

Returns whether this format supports import.

pub const fn supports_export(&self) -> bool

Returns whether this format supports export.

Trait Implementations

impl Clone for Format

fn clone(&self) -> Format

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Format

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Format

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl FromStr for Format

type Err = Error

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self>

Parses a string s to return a value of this type.

impl Hash for Format

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Format

fn eq(&self, other: &Format) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
