Struct precompile_utils::solidity::revert::Revert

pub struct Revert { /* private fields */ }

An revert returned by various functions in precompile-utils. Allows to dynamically construct the backtrace (backtrace) of the revert and manage it in a typed way. Can be transformed into a PrecompileFailure::Revert and String, and implement Display and Debug.

Implementations

impl Revert

pub fn new(reason: RevertReason) -> Self

Create a new Revert with a RevertReason and an empty backtrace.

pub fn change_what(self, what: impl Into<String>) -> Self

For all RevertReason variants that have a what field, change its value. Otherwise do nothing. It is useful when writing custom types solidity::Codec implementations using simpler types.

pub fn to_encoded_bytes(self) -> Vec<u8>

Transforms the revert into its bytes representation (from a String).

Trait Implementations

impl BacktraceExt for Revert

fn map_in_tuple_to_field(self, fields: &[&'static str]) -> Self

Map last tuple entry into a field. Does nothing if last entry is not a tuple. As in Solidity structs are equivalent to tuples and are tricky to parse correctly, it allows to parse any struct as a tuple (with the correct implementation in this crate) and then map tuple indices to struct fields.

impl Debug for Revert

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

Formats the value using the given formatter.

impl Display for Revert

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

Formats the value using the given formatter.

impl From<Revert> for PrecompileFailure

fn from(err: Revert) -> Self

Converts to this type from the input type.

impl From<Revert> for Vec<u8>

fn from(val: Revert) -> Self

Converts to this type from the input type.

impl From<RevertReason> for Revert

fn from(a: RevertReason) -> Revert

Converts to this type from the input type.

impl InjectBacktrace for Revert

type Output = Revert

Output type of the injection. Should be a type that can hold a backtrace.

fn in_field(self, field: impl Into<String>) -> Self

Occurs in a field.

fn in_array(self, index: usize) -> Self

Occurs in an array at provided index.

fn in_tuple(self, index: usize) -> Self

Occurs in a tuple.

impl PartialEq for Revert

fn eq(&self, other: &Revert) -> 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 RevertExt for Revert

fn map_reason(self, f: impl FnOnce(RevertReason) -> RevertReason) -> Self

Map the reason while keeping the same backtrace.
