Enum StrengthModifier 

Source

    Subtract(i32),
    Multiply(i32),
    Divide(i32),
    Set(i32),
}
Expand description

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
