Struct ValidValue 

pub struct ValidValue(/* private fields */);

Implementations

impl ValidValue

pub fn parse(s: f64) -> Result<ValidValue, ValidationError>

Returns ValidValue only if input satisfies validation criteria, otherwise panics.

Trait Implementations

impl AsRef<f64> for ValidValue

fn as_ref(&self) -> &f64

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for ValidValue

fn clone(&self) -> ValidValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ValidValue

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

Formats the value using the given formatter.

impl<'r, DB: Database> Decode<'r, DB> for ValidValue

where f64: Decode<'r, DB>,

fn decode( value: <DB as Database>::ValueRef<'r>, ) -> Result<Self, Box<dyn Error + Send + Sync + 'static>>

Decode a new value of this type using a raw value from the database.

impl<'de> Deserialize<'de> for ValidValue

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

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ValidValue

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

Formats the value using the given formatter.

impl<'q, DB: Database> Encode<'q, DB> for ValidValue

where f64: Encode<'q, DB>,

fn encode_by_ref( &self, buf: &mut <DB as Database>::ArgumentBuffer<'q>, ) -> Result<IsNull, BoxDynError>

Writes the value of self into buf without moving self.

fn produces(&self) -> Option<DB::TypeInfo>

fn size_hint(&self) -> usize

fn encode( self, buf: &mut <DB as Database>::ArgumentBuffer<'q>, ) -> Result<IsNull, Box<dyn Error + Sync + Send>>

where Self: Sized,

Writes the value of self into buf in the expected format for the database.

impl PartialEq for ValidValue

fn eq(&self, other: &ValidValue) -> 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 Serialize for ValidValue

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

where S: Serializer,

Serialize this value into the given Serde serializer.

impl Type<Postgres> for ValidValue

fn type_info() -> PgTypeInfo

Returns the canonical SQL type for this Rust type.

fn compatible(ty: &PgTypeInfo) -> bool

Determines if this Rust type is compatible with the given SQL type.

impl Copy for ValidValue

impl StructuralPartialEq for ValidValue
