Implementations

impl Input

pub fn get_requirements(&self) -> InputRequirements

Returns what kind of pre-computed image is needed as the input for a filter primitive.

In a filter value list, some primitives may reference a particular kind of source content with the in attribute. The code flow becomes easier by being able to render this source content before processing the filter value list.

Trait Implementations

impl Clone for Input

fn clone(&self) -> Input

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Input

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

Formats the value using the given formatter.

impl Default for Input

fn default() -> Input

Returns the “default value” for a type.

impl Hash for Input

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 Parse for Input

fn parse<'i>(parser: &mut Parser<'i, '_>) -> Result<Self, ParseError<'i>>

Parses a value out of the parser.

fn parse_str(s: &str) -> Result<Self, ParseError<'_>>

Convenience function to parse a value out of a &str.

impl PartialEq for Input

fn eq(&self, other: &Input) -> 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 Eq for Input
