Enum Value

pub enum Value {
    Value(i32),
    Tag(String),
}

Represents the possible nations for a value.

Variants

Value(i32)

A literal value.

Tag(String)

A reference to a LineType::Tag value E.G. $SomeTag.

Implementations

impl Value

pub fn parse(value: &str) -> Result<Value, ValueParseError>

Tried to parse a value expression into an instance of Value.

Returns [Ok(Value)] if there is a valid value detected, returns an [Err(ValueParseError)] if the value is invalid, detailing what is wrong.

Can parse

• Hex - 0xA = 10
• Decimal - 0d10 = 10
• Octal - 0o12 = 10
• Binary - 0b1010 = 10
• Tags - $foo = “foo”

pub fn parse_hex(value: String) -> Result<Value, ValueParseError>

Tries to parse a hex string.

Returns a ValueParseError if it fails.

pub fn parse_decimal(value: String) -> Result<Value, ValueParseError>

Tries to parse a decimal string.

Returns a ValueParseError if it fails.

pub fn parse_octal(value: String) -> Result<Value, ValueParseError>

Tries to parse an octal string.

Returns a ValueParseError if it fails.

pub fn parse_binary(value: String) -> Result<Value, ValueParseError>

Tries to parse a binary string.

Returns a ValueParseError if it fails.

pub fn parse_tag_name(v: String) -> Result<Value, ValueParseError>

Tries to parse a tag reference.

Returns a ValueParseError if it contains any whitespace.

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 PartialEq for Value

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