Struct rustler::types::atom::Atom

pub struct Atom { /* private fields */ }

Implementations

impl Atom

pub fn as_c_arg(self) -> NIF_TERM

pub fn to_term(self, env: Env<'_>) -> Term<'_>

pub fn from_term(term: Term<'_>) -> NifResult<Self>

pub fn from_bytes(env: Env<'_>, bytes: &[u8]) -> NifResult<Atom>

Return the atom whose text representation is bytes, like erlang:binary_to_atom/2.

Errors

Error::BadArg if bytes.len() > 255.

pub fn try_from_bytes(env: Env<'_>, bytes: &[u8]) -> NifResult<Option<Atom>>

Return the atom whose text representation is bytes, like erlang:binary_to_existing_atom/2, if atom with given text representation exists.

Errors

Error::BadArg if bytes.len() > 255.

pub fn from_str(env: Env<'_>, string: &str) -> NifResult<Atom>

Return the atom whose text representation is the given string, like erlang:list_to_atom/2.

Errors

Error::BadArg if string contains characters that aren’t in Latin-1, or if it’s too long. The maximum length is 255 characters.

Trait Implementations

impl Clone for Atom

fn clone(&self) -> Atom

Returns a copy 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<(), Error>

Formats the value using the given formatter.

impl<'a> Decoder<'a> for Atom

fn decode(term: Term<'a>) -> NifResult<Atom>

impl Encoder for Atom

fn encode<'a>(&self, env: Env<'a>) -> Term<'a>

impl<'a> PartialEq<Term<'a>> for Atom

fn eq(&self, other: &Term<'a>) -> 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 PartialEq for Atom

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