Enum RawRansError 

pub enum RawRansError {
    InvalidScaleBits {
        provided: u32,
        max_safe: u32,
    },
    InvalidParameters,
}

Errors that can occur during raw rANS operations.

Variants

InvalidScaleBits

scale_bits is out of the valid range for the variant.

For RansByte: valid range is [2, 30]. For Rans64: the defined safe range is [2, 31]. scale_bits == 32 causes undefined-shift behavior in the C++ oracle and is rejected by this implementation.

Fields

provided: u32

The provided scale_bits value.

max_safe: u32

The maximum safe value for this variant.

InvalidParameters

Frequency or start values are out of range.
