Enum StrengthModifier 

pub enum StrengthModifier {
    Add(i32),
    Subtract(i32),
    Multiply(i32),
    Divide(i32),
    Set(i32),
}

Strength modifier for magic rules

Strength modifiers adjust the default strength calculation for a rule. They are specified using the !:strength directive in magic files.

Examples

use libmagic_rs::parser::ast::StrengthModifier;

let add = StrengthModifier::Add(10);      // !:strength +10
let sub = StrengthModifier::Subtract(5);  // !:strength -5
let mul = StrengthModifier::Multiply(2);  // !:strength *2
let div = StrengthModifier::Divide(2);    // !:strength /2
let set = StrengthModifier::Set(50);      // !:strength =50

Variants

Add(i32)

Add to the default strength: !:strength +N

Subtract(i32)

Subtract from the default strength: !:strength -N

Multiply(i32)

Multiply the default strength: !:strength *N

Divide(i32)

Divide the default strength: !:strength /N

Set(i32)

Set strength to an absolute value: !:strength =N or !:strength N

Trait Implementations

impl Clone for StrengthModifier

fn clone(&self) -> StrengthModifier

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StrengthModifier

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for StrengthModifier

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for StrengthModifier

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

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 StrengthModifier
