Struct precompile_utils::solidity::revert::Revert

source · 
pub struct Revert { /* private fields */ }
Expand description

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§

source§

impl Revert

source

pub fn new(reason: RevertReason) -> Self

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

source

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.

source

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

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

Trait Implementations§

source§

impl BacktraceExt for Revert

source§

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.
