Struct ScalarValueRef 

pub struct ScalarValueRef<'a> { /* private fields */ }

Borrowed view over a scalar value backed by DynCellRef.

Implementations

impl<'a> ScalarValueRef<'a>

pub fn is_null(&self) -> bool

Returns true when the literal is the Null variant.

pub fn compare(&self, other: &ScalarValueRef<'_>) -> Option<Ordering>

Compares this scalar with another, returning the ordering when both sides are comparable.

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

Extract as bool when possible.

pub fn as_int_i128(&self) -> Option<i128>

Extract as signed integer across supported widths.

pub fn as_uint_u128(&self) -> Option<u128>

Extract as unsigned integer across supported widths.

pub fn as_f64(&self) -> Option<f64>

Extract as 64-bit floating point.

pub fn as_utf8(&self) -> Option<&'a str>

Extract as string slice.

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

Extract as binary slice.

pub fn as_dyn(&self) -> DynCellRef<'a>

Access the underlying dynamic cell reference.

pub fn from_dyn(cell: DynCellRef<'a>) -> Self

Construct from a dynamic cell reference.

Trait Implementations

impl<'a> Clone for ScalarValueRef<'a>

fn clone(&self) -> ScalarValueRef<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for ScalarValueRef<'a>

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

Formats the value using the given formatter.

impl<'a> PartialEq for ScalarValueRef<'a>

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.

impl PartialEq<DynCellRef<'_>> for ScalarValueRef<'_>

fn eq(&self, other: &DynCellRef<'_>) -> 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 ScalarValueRef<'_>

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

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

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.
