Struct MustBeText 

pub struct MustBeText<M: MustBeTextMarker>(/* private fields */);

Zero-sized type that only parses from a specific Text value.

This type implements FromEure and succeeds only when the parsed value matches the expected content and has a compatible language.

Use the MustBeText! macro to create instances of this type.

Implementations

impl<M: MustBeTextMarker> MustBeText<M>

pub const fn new() -> Self

Create a new instance.

Trait Implementations

impl<M: Clone + MustBeTextMarker> Clone for MustBeText<M>

fn clone(&self) -> MustBeText<M>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<M: Debug + MustBeTextMarker> Debug for MustBeText<M>

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

Formats the value using the given formatter.

impl<M: Default + MustBeTextMarker> Default for MustBeText<M>

fn default() -> MustBeText<M>

Returns the “default value” for a type.

impl<M: MustBeTextMarker> FromEure<'_> for MustBeText<M>

type Error = ParseError

The error type returned by parsing.

fn parse(ctx: &ParseContext<'_>) -> Result<Self, Self::Error>

Parse a value of type T from the given parse context.

impl<M: Hash + MustBeTextMarker> Hash for MustBeText<M>

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<M: PartialEq + MustBeTextMarker> PartialEq for MustBeText<M>

fn eq(&self, other: &MustBeText<M>) -> 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<M: Copy + MustBeTextMarker> Copy for MustBeText<M>

impl<M: Eq + MustBeTextMarker> Eq for MustBeText<M>

impl<M: MustBeTextMarker> StructuralPartialEq for MustBeText<M>
