Enum SnapVersion 

#[repr(u8)]
pub enum SnapVersion {
    V2 = 2,
}

Supported SNAP protocol versions.

Variants

V2 = 2

BAL-based healing as proposed by EIP-8189.

Implementations

impl SnapVersion

pub const fn message_count(self) -> u8

Returns the protocol message slot length for this version (not the count of valid ids; use Self::supports_message_id to check validity).

pub const fn supports_message_id(self, id: u8) -> bool

Returns true if id is a valid snap/2 message id.

snap/2 (EIP-8189) drops trie nodes (0x06/0x07) and adds BAL (0x08/0x09), so validity is not a contiguous range.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
