Implementations

impl EofHeader

pub fn size(&self) -> usize

Gets the length of the header in bytes.

It is minimum 15 bytes (there is at least one code section).

pub fn data_size_raw_i(&self) -> usize

Returns index where data size starts.

Data size is two bytes long.

pub fn types_count(&self) -> usize

Returns number of types.

pub fn body_size(&self) -> usize

Returns body size.

It is sum of code sizes, container sizes and data size.

pub fn eof_size(&self) -> usize

Returns raw size of the EOF.

pub fn encode(&self, buffer: &mut Vec<u8>)

Encodes EOF header into binary form.

pub fn decode(input: &[u8]) -> Result<(EofHeader, &[u8]), EofDecodeError>

Decodes EOF header from binary form. Format of the code section is: 0xEF000101 | u16 | 0x02 | u16 | u16 * cnum | 0x03 | u16 | cnum* u32 | 0xff | u16 | 0x00

Trait Implementations

impl Clone for EofHeader

fn clone(&self) -> EofHeader

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EofHeader

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

Formats the value using the given formatter.

impl Default for EofHeader

fn default() -> EofHeader

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for EofHeader

fn deserialize<__D>( __deserializer: __D, ) -> Result<EofHeader, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for EofHeader

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,

Feeds a slice of this type into the given Hasher.

impl Ord for EofHeader

fn cmp(&self, other: &EofHeader) -> 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 EofHeader

fn eq(&self, other: &EofHeader) -> 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 EofHeader

fn partial_cmp(&self, other: &EofHeader) -> 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.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for EofHeader

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for EofHeader

impl StructuralPartialEq for EofHeader

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
