Implementations

impl Value

pub fn as_int(&self) -> Option<i64>

Try to extract an integer from this value

pub fn as_binary(&self) -> Option<&[u8]>

Try to extract a binary from this value

pub fn to_bigint(&self) -> Option<BigInt>

Convert to BigInt if this is any integer type

pub fn from_bigint(n: BigInt) -> Value

Create a Value from a BigInt, normalizing to Int if it fits

pub fn is_zero(&self) -> bool

Check if this value is zero (for Int or BigInt)

Trait Implementations

impl Clone for Value

fn clone(&self) -> Value

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Value

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

Formats the value using the given formatter.

impl From<f64> for Value

fn from(f: f64) -> Self

Converts to this type from the input type.

impl From<i64> for Value

fn from(n: i64) -> Self

Converts to this type from the input type.

impl Hash for Value

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

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 PartialEq for Value

fn eq(&self, other: &Self) -> 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.
