Enum Atom

pub enum Atom {
    UUID(UUID),
    Integer(i64),
    Float(f64),
    String(String),
}

An Atom in RON is an immutable value of one of the types: UUID, integer, string and float.

Variants

UUID(UUID)

References another object

Integer(i64)

Signed integer. RON specifies arbitrary precision integer, we only support up to 64 bits.

Float(f64)

IEEE 754 Floating point number.

String(String)

UTF-8 String

Implementations

impl Atom

pub fn is_uuid(&self) -> bool

Return true if and only if this is an UUID atom.

pub fn is_integer(&self) -> bool

Return true if and only if this is an Integer atom.

pub fn is_float(&self) -> bool

Return true if and only if this is a Float atom.

pub fn is_string(&self) -> bool

Return true if and only if this is a String atom.

pub fn parse<'a>( input: &'a str, context: Option<(&UUID, &UUID)>, ) -> Option<(Self, &'a str)>

Parse a single atom, returning the Atom and the remaining string. If context is not None UUID Atoms may be compressed against (previous column UUID / previous row UUID).

Trait Implementations

impl Clone for Atom

fn clone(&self) -> Atom

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Atom

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

Formats the value using the given formatter.

impl Display for Atom

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

Formats the value using the given formatter.

impl Hash for Atom

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 Atom

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