Struct ShortString 

pub struct ShortString;

A value schema for a short string. A short string is a UTF-8 encoded string with a maximum length of 32 bytes (inclusive) The string is null-terminated. If the string is shorter than 32 bytes, the remaining bytes are zero. If the string is exactly 32 bytes, then there is no zero terminator.

Trait Implementations

impl ConstDescribe for ShortString

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

where B: BlobStore<Blake3>,

Produces a Fragment describing this schema type.

impl ConstId for ShortString

const ID: Id

The stable 128-bit identifier for this type.

impl ToValue<ShortString> for &String

fn to_value(self) -> Value<ShortString>

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<ShortString> for &str

fn to_value(self) -> Value<ShortString>

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<ShortString> for String

fn to_value(self) -> Value<ShortString>

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, ShortString> for &'a str

type Error = Utf8Error

The error type returned when the conversion fails.

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

Convert the Value with a specific schema type to the Rust type.

impl<'a> TryFromValue<'a, ShortString> for String

type Error = Utf8Error

The error type returned when the conversion fails.

fn try_from_value(v: &Value<ShortString>) -> Result<Self, Self::Error>

Convert the Value with a specific schema type to the Rust type.

impl TryToValue<ShortString> for &str

type Error = FromStrError

The error type returned when the conversion fails.

fn try_to_value(self) -> Result<Value<ShortString>, 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<ShortString> for String

type Error = FromStrError

The error type returned when the conversion fails.

fn try_to_value(self) -> Result<Value<ShortString>, 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 ShortString

type ValidationError = ValidationError

The error type returned by validate. Use () or Infallible when every bit pattern is valid.

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.
