Trait IsZero

pub trait IsZero {
    // Required method
    fn is_zero(&self) -> bool;
}

Trait defining instance method is_zero() : bool that indicates whether the implementing type instance is numerically zero.

Additional Implementations on Foreign Types

Built-in Types

If the feature "implement-IsZero-for-built_ins" is defined (as it is by "default"), then this is also implemented for the following types:

• i8;
• i16;
• i32;
• i64;
• i128;
• u8;
• u16;
• u32;
• u64;
• u128;
• isize;
• usize;
• f32;
• f64;
• char;

Standard Process Types

If the feature "implement-IsZero-for-standard_process_types" is defined (as it is by "default"), then this is also implemented for the following types:

• std::process::ExitStatus;

Standard Time Types

If the feature "implement-IsZero-for-standard_time_types" is defined (as it is by "default"), then this is also implemented for the following types:

• std::time::Duration;
