Struct serde_bool::True

pub struct True;

Type that only deserializes from the true boolean value.

Examples

assert_eq!(
    serde_json::from_str::<serde_bool::True>("true").unwrap().as_bool(),
    true,
);

serde_json::from_str::<serde_bool::True>("false").unwrap_err();
serde_json::from_str::<serde_bool::True>("42").unwrap_err();

Implementations

impl True

pub const fn as_bool(self) -> bool

Returns true.

Trait Implementations

impl Clone for True

fn clone(&self) -> True

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for True

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

Formats the value using the given formatter.

impl Default for True

fn default() -> True

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for True

fn deserialize<D: Deserializer<'de>>(deserializer: D) -> Result<Self, D::Error>

Deserialize this value from the given Serde deserializer.

impl From<True> for bool

fn from(_: True) -> Self

Converts to this type from the input type.

impl PartialEq<False> for True

fn eq(&self, _: &False) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialEq<True> for False

fn eq(&self, _: &True) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialEq<True> for bool

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialEq<bool> for True

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialEq for True

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for True

fn serialize<S: Serializer>(&self, serializer: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.

impl Copy for True

impl Eq for True

impl StructuralEq for True

impl StructuralPartialEq for True
