Enum PackError 

#[non_exhaustive]
pub enum PackError {
    LengthTooLarge {
        segment: usize,
        length: u32,
    },
    ValueTooLarge {
        segment: usize,
        value: u32,

    },
}

Pack errors raised by the host-side packer.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

LengthTooLarge

Segment length exceeded the 24-bit field budget.

Fields

segment: usize

The segment index whose length overflowed.

length: u32

The length that exceeded MAX_SEGMENT_LENGTH.

ValueTooLarge

Segment value exceeded the 8-bit field budget.

Fields

segment: usize

The segment index whose value overflowed.

value: u32

The value that exceeded MAX_SEGMENT_VALUE.

AllocationFailed

Caller-owned output storage could not be reserved.

Fields

message: String

Allocator or capacity diagnostic.
