Struct Boolean 

pub struct Boolean;

Value schema that stores boolean flags as either all-zero or all-one bit patterns.

Storing false as 0x00 and true as 0xFF in every byte makes it trivial to distinguish the two cases while leaving room for future SIMD optimisations when scanning large collections of flags.

Trait Implementations

impl ConstMetadata for Boolean

fn id() -> Id

Returns the root identifier for this metadata description.

fn describe<B>(blobs: &mut B) -> Result<TribleSet, B::PutError>

where B: BlobStore<Blake3>,

impl<'a> FromValue<'a, Boolean> for bool

fn from_value(v: &'a Value<Boolean>) -> Self

Convert the Value with a specific schema type to the Rust type. This might cause a panic if the conversion is not possible.

impl ToValue<Boolean> for &bool

fn to_value(self) -> Value<Boolean>

Convert the Rust type to a Value with a specific schema type. This might cause a panic if the conversion is not possible.

impl ToValue<Boolean> for bool

fn to_value(self) -> Value<Boolean>

Convert the Rust type to a Value with a specific schema type. This might cause a panic if the conversion is not possible.

impl<'a> TryFromValue<'a, Boolean> for bool

type Error = InvalidBoolean

fn try_from_value(v: &'a Value<Boolean>) -> Result<Self, Self::Error>

Convert the Value with a specific schema type to the Rust type. This might return an error if the conversion is not possible.

impl TryToValue<Boolean> for &bool

type Error = Infallible

fn try_to_value(self) -> Result<Value<Boolean>, Self::Error>

Convert the Rust type to a Value with a specific schema type. This might return an error if the conversion is not possible.

impl TryToValue<Boolean> for bool

type Error = Infallible

fn try_to_value(self) -> Result<Value<Boolean>, Self::Error>

Convert the Rust type to a Value with a specific schema type. This might return an error if the conversion is not possible.

impl ValueSchema for Boolean

type ValidationError = InvalidBoolean

fn validate(value: Value<Self>) -> Result<Value<Self>, Self::ValidationError>

Check if the given value conforms to this schema.

fn value_from<T: ToValue<Self>>(t: T) -> Value<Self>

Create a new value from a concrete Rust type. This is a convenience method that calls the ToValue trait. This method might panic if the conversion is not possible.

fn value_try_from<T: TryToValue<Self>>( t: T, ) -> Result<Value<Self>, <T as TryToValue<Self>>::Error>

Create a new value from a concrete Rust type. This is a convenience method that calls the TryToValue trait. This method might return an error if the conversion is not possible.
