Implementations

impl TLVValueType

pub const fn fixed_size(&self) -> Option<usize>

Return the size of the value corresponding to this value type.

If the value type has a variable size (i.e. octet and Utf8 strings), this function returns None.

pub const fn variable_size_len(&self) -> usize

Return the size of the length field for variable size value types.

if the value type has a fixed size, this function returns 0. Variable size types are only octet strings and utf8 strings.

pub const fn is_container(&self) -> bool

Convenience method to check if the value type is a container type (container start or end).

pub const fn is_container_start(&self) -> bool

Convenience method to check if the value type is a container start type.

pub const fn is_container_end(&self) -> bool

Convenience method to check if the value type is a container end type.

pub const fn is_str(&self) -> bool

Convenience method to check if the value type is an Octet String type.

pub const fn is_utf8(&self) -> bool

Convenience method to check if the value type is a UTF-8 String type.

pub fn container_value<'a>(&self) -> Result<TLVValue<'a>, Error>

Trait Implementations

impl Clone for TLVValueType

fn clone(&self) -> TLVValueType

fn from_u64(n: u64) -> Option<TLVValueType>

Converts an u64 to return an optional value of this type. If the value cannot be represented by this type, then None is returned.

fn from_isize(n: isize) -> Option<Self>

Converts an isize to return an optional value of this type. If the value cannot be represented by this type, then None is returned.

fn from_i8(n: i8) -> Option<Self>

Converts an i8 to return an optional value of this type. If the value cannot be represented by this type, then None is returned.

fn from_i16(n: i16) -> Option<Self>

Converts an i16 to return an optional value of this type. If the value cannot be represented by this type, then None is returned.

fn from_i32(n: i32) -> Option<Self>

Converts an i32 to return an optional value of this type. If the value cannot be represented by this type, then None is returned.

fn from_i128(n: i128) -> Option<Self>

Converts an i128 to return an optional value of this type. If the value cannot be represented by this type, then None is returned.

impl Hash for TLVValueType

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

impl Ord for TLVValueType

fn cmp(&self, other: &TLVValueType) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for TLVValueType

fn eq(&self, other: &TLVValueType) -> 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 PartialOrd for TLVValueType

fn partial_cmp(&self, other: &TLVValueType) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.
