Struct FormatInfo 

#[non_exhaustive]
pub struct FormatInfo {
    pub token: &'static str,
    pub extension: Option<&'static str>,
    pub is_directory: bool,
    pub can_emit: bool,
}

The canonical identity and destination shape of a PowerIO format.

extension is the conventional filename suffix without a leading dot; it may be compound. It is None for directory formats with no primary case file. can_emit reports whether a fresh universal emitter exists for the format. It does not promise that every concrete module value can emit that format, and it is not a build feature probe. A false value neither promises nor forbids a same format retained source echo.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

token: &'static str

Canonical stable token used by parse and emit operations when the current build and concrete value support the format.

extension: Option<&'static str>

Conventional filename suffix without a leading dot.

is_directory: bool

Whether a path destination names an output directory rather than one file.

can_emit: bool

Whether a fresh universal emitter exists for this format.

Trait Implementations

impl Clone for FormatInfo

fn clone(&self) -> FormatInfo

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for FormatInfo

impl Debug for FormatInfo

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

Formats the value using the given formatter.

impl Eq for FormatInfo

impl PartialEq for FormatInfo

fn eq(&self, other: &FormatInfo) -> 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.

impl Serialize for FormatInfo

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
