Struct TransactionType 

pub struct TransactionType(/* private fields */);

EIP-2718 transaction envelope type.

Implementations

impl TransactionType

pub const LEGACY: Self

Legacy transaction type used by APIs that need an explicit domain value.

pub const MAX_TYPED: u8 = 0x7f

Largest typed transaction value admitted by EIP-2718.

pub const fn try_new_typed(value: u8) -> Result<Self, PrimitiveError>

Creates a typed EIP-2718 transaction type.

0 is reserved for the legacy transaction domain. Encoders must handle legacy transactions separately instead of prepending a zero type byte.

pub const fn try_new_with_legacy(value: u8) -> Result<Self, PrimitiveError>

Creates a transaction type and accepts the legacy domain marker.

Use this when an API explicitly accepts both legacy and typed transaction domains. Use Self::try_new_typed when parsing an EIP-2718 typed-envelope byte.

pub const fn get(self) -> u8

Returns the raw transaction type byte.

Trait Implementations

impl Clone for TransactionType

fn clone(&self) -> TransactionType

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for TransactionType

impl Debug for TransactionType

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for TransactionType

impl From<TransactionType> for u8

fn from(value: TransactionType) -> Self

Converts to this type from the input type.

impl Hash for TransactionType

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for TransactionType

fn cmp(&self, other: &TransactionType) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for TransactionType

fn eq(&self, other: &TransactionType) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for TransactionType

fn partial_cmp(&self, other: &TransactionType) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl StructuralPartialEq for TransactionType

impl TryFrom<u8> for TransactionType

fn try_from(value: u8) -> Result<Self, Self::Error>

Parses a typed EIP-2718 transaction type byte.

Rejects 0 because it belongs to the legacy transaction domain. Use TransactionType::try_new_with_legacy when the caller explicitly accepts both legacy and typed transaction domains.

type Error = PrimitiveError

The type returned in the event of a conversion error.
