Struct ValueTransform 

pub struct ValueTransform {
    pub op: ValueTransformOp,
    pub operand: i64,
}

A pre-comparison value transform: (op, operand).

Applied to the value read from the file before the rule’s comparison operator runs. See ValueTransformOp for the supported operations.

Examples

use libmagic_rs::parser::ast::{ValueTransform, ValueTransformOp};

// `lelong+1` -> add 1 to the read value
let t = ValueTransform { op: ValueTransformOp::Add, operand: 1 };
assert_eq!(t.op, ValueTransformOp::Add);
assert_eq!(t.operand, 1);

Fields

op: ValueTransformOp

Operation to apply.

operand: i64

Operand to combine with the read value.

Trait Implementations

impl Clone for ValueTransform

fn clone(&self) -> ValueTransform

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ValueTransform

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ValueTransform

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ValueTransform

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for ValueTransform

impl Eq for ValueTransform
