Enum StrLen 

pub enum StrLen {
    LengthPrefixed,
    NullTerminated,
    NullTerminatedFixed(usize),
}

The encoding method use for the length of a string.

Variants

LengthPrefixed

The length of the string is stored before its contents as an usize.

NullTerminated

The length of the string is obtained by finding the first occurrence of n number of null bytes, where n is the length in bytes of one code unit for the given string encoding (see StrEncoding::bytes).

NullTerminatedFixed(usize)

Like StrLen::NullTerminated, but the string always occupies n bytes, where the last bytes are filled with null-bytes if the length of the string after being encoded is less than n bytes.

Trait Implementations

impl Clone for StrLen

fn clone(&self) -> StrLen

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StrLen

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

Formats the value using the given formatter.

impl Default for StrLen

fn default() -> StrLen

Returns the “default value” for a type.

impl Display for StrLen

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

Formats the value using the given formatter.

impl Hash for StrLen

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 StrLen

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