Struct BigInt 

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

A signed 64-bit integer that travels as a canonical decimal string on every codec. See the module documentation for the wire form.

Implementations

impl BigInt

Trait Implementations

impl Clone for BigInt

fn clone(&self) -> BigInt

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for BigInt

impl Debug for BigInt

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

impl Default for BigInt

fn default() -> BigInt

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for BigInt

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

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for BigInt

i64’s own formatting, so every value written without flags is canonical.

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

Formats the value using the given formatter.

impl Encode<'_, Postgres> for BigInt

fn encode_by_ref( &self, buf: &mut PgArgumentBuffer, ) -> Result<IsNull, Box<dyn Error + Send + Sync>>

Writes the value of self into buf without moving self.

fn size_hint(&self) -> usize

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

where Self: Sized,

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

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

impl Eq for BigInt

impl From<i64> for BigInt

fn from(value: i64) -> BigInt

Converts to this type from the input type.

impl FromSql for BigInt

fn column_result(value: ValueRef<'_>) -> Result<BigInt, FromSqlError>

Converts SQLite value into Rust value.

impl FromStr for BigInt

Parses the canonical decimal form only; see ParseBigIntError.

type Err = ParseBigIntError

The associated error which can be returned from parsing.

fn from_str(text: &str) -> Result<BigInt, <BigInt as FromStr>::Err>

Parses a string s to return a value of this type.

impl Hash for BigInt

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

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 IntoSqlValue for BigInt

The BigInt scalar (ADR 0019). Also what lets a BigInt @id or a BigInt foreign key satisfy the rusqlite delegates’ IntoSqlValue primary-key bound.

fn into_sql_value(self) -> SqlValue

impl Ord for BigInt

fn cmp(&self, other: &BigInt) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for BigInt

fn eq(&self, other: &BigInt) -> 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 PartialOrd for BigInt

fn partial_cmp(&self, other: &BigInt) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
