Struct FileOption

pub struct FileOption(/* private fields */);

Similar to the File struct, used for the fixed-length Message file field, but is a variable-length option used for the Message options field.

A null-terminated string with min-length 1.

Implementations

impl FileOption

pub fn new(name: &CStr) -> Result<Self>

Construct a valid file field.

pub fn to_string(self) -> CString

Get the CString that this type wraps.

pub fn len(&self) -> usize

Get the length of FileOption (WITH the null byte).

pub fn extend_into(&self, bytes: &mut Vec<u8>, tag: u8)

Used to encode the variable-length option.

Trait Implementations

impl Clone for FileOption

fn clone(&self) -> FileOption

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FileOption

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for FileOption

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<&[u8]> for FileOption

fn from(value: &[u8]) -> Self

Converts to this type from the input type.

impl PartialEq for FileOption

fn eq(&self, other: &FileOption) -> 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 Serialize for FileOption

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
