Enum PStringLengthWidth 

#[non_exhaustive]
pub enum PStringLengthWidth {
    OneByte,
    TwoByteBE,
    TwoByteLE,
    FourByteBE,
    FourByteLE,
}

The width of the length prefix for Pascal strings.

Uppercase suffix letters (/H, /L) indicate big-endian byte order. Lowercase suffix letters (/h, /l) indicate little-endian byte order.

Examples

use libmagic_rs::parser::ast::PStringLengthWidth;
let width = PStringLengthWidth::OneByte;
assert_eq!(width.byte_count(), 1);

let width = PStringLengthWidth::TwoByteBE;
assert_eq!(width.byte_count(), 2);

let width = PStringLengthWidth::FourByteLE;
assert_eq!(width.byte_count(), 4);

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

OneByte

1-byte length prefix (default, /B suffix)

Examples

use libmagic_rs::parser::ast::PStringLengthWidth;
let width = PStringLengthWidth::OneByte;
assert_eq!(width.byte_count(), 1);

TwoByteBE

2-byte big-endian length prefix (/H suffix)

Examples

use libmagic_rs::parser::ast::PStringLengthWidth;
let width = PStringLengthWidth::TwoByteBE;
assert_eq!(width.byte_count(), 2);

TwoByteLE

2-byte little-endian length prefix (/h suffix)

Examples

use libmagic_rs::parser::ast::PStringLengthWidth;
let width = PStringLengthWidth::TwoByteLE;
assert_eq!(width.byte_count(), 2);

FourByteBE

4-byte big-endian length prefix (/L suffix)

Examples

use libmagic_rs::parser::ast::PStringLengthWidth;
let width = PStringLengthWidth::FourByteBE;
assert_eq!(width.byte_count(), 4);

FourByteLE

4-byte little-endian length prefix (/l suffix)

Examples

use libmagic_rs::parser::ast::PStringLengthWidth;
let width = PStringLengthWidth::FourByteLE;
assert_eq!(width.byte_count(), 4);

Implementations

impl PStringLengthWidth

pub fn byte_count(&self) -> usize

Returns the number of bytes used for the length prefix.

Trait Implementations

impl Clone for PStringLengthWidth

fn clone(&self) -> PStringLengthWidth

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for PStringLengthWidth

impl Debug for PStringLengthWidth

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PStringLengthWidth

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for PStringLengthWidth

impl PartialEq for PStringLengthWidth

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
