Implementations

impl Value

pub fn as_string(&self) -> Option<&str>

Returns the entity value as a string, or None if the value the wrong type.

pub fn as_int(&self) -> Option<i32>

Returns the entity value as an int, or None if the value the wrong type.

pub fn as_big_decimal(&self) -> Option<&BigDecimal>

Returns the entity value as a big decimal, or None if the value the wrong type.

pub fn as_bool(&self) -> Option<bool>

Returns the entity value as a bool, or None if the value the wrong type.

pub fn as_array(&self) -> Option<&[Value]>

Returns the entity value as an array, or None if the value the wrong type.

pub fn as_null(&self) -> Option<()>

Returns the entity value as null, or None if the value the wrong type.

pub fn as_bytes(&self) -> Option<&Vec<u8>>

Returns the entity value as bytes, or None if the value the wrong type.

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

Returns the entity value as a big int, or None if the value the wrong type.

Trait Implementations

impl Clone for Value

fn clone(&self) -> Value

Returns a copy 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 Default for Value

fn default() -> Value

Returns the “default value” for a type.

impl PartialEq<Value> for Value

fn eq(&self, other: &Value) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Eq for Value

impl StructuralEq for Value
