Trait CheckedOps 

pub trait CheckedOps: Sized {
    // Required methods
    fn checked_add_offset(self, offset: Self) -> FsResult<Self>;
    fn checked_mul_size(self, size: Self) -> FsResult<Self>;
    fn checked_sub_safe(self, other: Self) -> FsResult<Self>;
    fn checked_shl_safe(self, shift: u32) -> FsResult<Self>;
}

Trait for checked arithmetic operations.

Provides methods that return FsError::ArithmeticOverflow on overflow instead of panicking or wrapping.

Required Methods

fn checked_add_offset(self, offset: Self) -> FsResult<Self>

Adds an offset, returning an error on overflow.

fn checked_mul_size(self, size: Self) -> FsResult<Self>

Multiplies by a size, returning an error on overflow.

fn checked_sub_safe(self, other: Self) -> FsResult<Self>

Subtracts, returning an error on underflow.

fn checked_shl_safe(self, shift: u32) -> FsResult<Self>

Left-shifts, returning an error if bits would be lost.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
