Enum cosmos_sdk_proto::cosmos::tx::signing::v1beta1::SignMode

#[repr(i32)]
pub enum SignMode {
    Unspecified = 0,
    Direct = 1,
    Textual = 2,
    DirectAux = 3,
    LegacyAminoJson = 127,
    Eip191 = 191,
}

SignMode represents a signing mode with its own security guarantees.

This enum should be considered a registry of all known sign modes in the Cosmos ecosystem. Apps are not expected to support all known sign modes. Apps that would like to support custom sign modes are encouraged to open a small PR against this file to add a new case to this SignMode enum describing their sign mode so that different apps have a consistent version of this enum.

Variants

Unspecified = 0

SIGN_MODE_UNSPECIFIED specifies an unknown signing mode and will be rejected.

Direct = 1

SIGN_MODE_DIRECT specifies a signing mode which uses SignDoc and is verified with raw bytes from Tx.

Textual = 2

SIGN_MODE_TEXTUAL is a future signing mode that will verify some human-readable textual representation on top of the binary representation from SIGN_MODE_DIRECT. It is currently not supported.

DirectAux = 3

SIGN_MODE_DIRECT_AUX specifies a signing mode which uses SignDocDirectAux. As opposed to SIGN_MODE_DIRECT, this sign mode does not require signers signing over other signers’ signer_info. It also allows for adding Tips in transactions.

Since: cosmos-sdk 0.46

LegacyAminoJson = 127

SIGN_MODE_LEGACY_AMINO_JSON is a backwards compatibility mode which uses Amino JSON and will be removed in the future.

Eip191 = 191

SIGN_MODE_EIP_191 specifies the sign mode for EIP 191 signing on the Cosmos SDK. Ref: https://eips.ethereum.org/EIPS/eip-191

Currently, SIGN_MODE_EIP_191 is registered as a SignMode enum variant, but is not implemented on the SDK by default. To enable EIP-191, you need to pass a custom TxConfig that has an implementation of SignModeHandler for EIP-191. The SDK may decide to fully support EIP-191 in the future.

Since: cosmos-sdk 0.45.2

Implementations

impl SignMode

pub fn is_valid(value: i32) -> bool

Returns true if value is a variant of SignMode.

pub fn from_i32(value: i32) -> Option<SignMode>

👎Deprecated: Use the TryFrom<i32> implementation instead

Converts an i32 to a SignMode, or None if value is not a valid variant.

impl SignMode

pub fn as_str_name(&self) -> &'static str

String value of the enum field names used in the ProtoBuf definition.

The values are not transformed in any way and thus are considered stable (if the ProtoBuf definition does not change) and safe for programmatic use.

Trait Implementations

impl Clone for SignMode

fn clone(&self) -> SignMode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SignMode

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

Formats the value using the given formatter.

impl Default for SignMode

fn default() -> SignMode

Returns the “default value” for a type.

impl From<SignMode> for i32

fn from(value: SignMode) -> i32

Converts to this type from the input type.

impl Hash for SignMode

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 SignMode

fn cmp(&self, other: &SignMode) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for SignMode

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for SignMode

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl TryFrom<i32> for SignMode

type Error = DecodeError

The type returned in the event of a conversion error.

fn try_from(value: i32) -> Result<SignMode, DecodeError>

Performs the conversion.

impl Copy for SignMode

impl Eq for SignMode

impl StructuralPartialEq for SignMode
