Trait Implementations§

Returns a copy of the value. Read more
Performs copy-assignment from source. Read more
Formats the value using the given formatter. Read more
This method tests for self and other values to be equal, and is used by ==. Read more
This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason. Read more
Converts the value of self to an i64. If the value cannot be represented by an i64, then None is returned. Read more
Converts the value of self to a u64. If the value cannot be represented by a u64, then None is returned. Read more
Converts the value of self to an isize. If the value cannot be represented by an isize, then None is returned. Read more
Converts the value of self to an i8. If the value cannot be represented by an i8, then None is returned. Read more
Converts the value of self to an i16. If the value cannot be represented by an i16, then None is returned. Read more
Converts the value of self to an i32. If the value cannot be represented by an i32, then None is returned. Read more
Converts the value of self to an i128. If the value cannot be represented by an i128 (i64 under the default implementation), then None is returned. Read more
Converts the value of self to a usize. If the value cannot be represented by a usize, then None is returned. Read more
Converts the value of self to a u8. If the value cannot be represented by a u8, then None is returned. Read more
Converts the value of self to a u16. If the value cannot be represented by a u16, then None is returned. Read more
Converts the value of self to a u32. If the value cannot be represented by a u32, then None is returned. Read more
Converts the value of self to a u128. If the value cannot be represented by a u128 (u64 under the default implementation), then None is returned. Read more
Converts the value of self to an f32. Overflows may map to positive or negative inifinity, otherwise None is returned if the value cannot be represented by an f32. Read more
Converts the value of self to an f64. Overflows may map to positive or negative inifinity, otherwise None is returned if the value cannot be represented by an f64. Read more
