Struct UpdateModification

#[non_exhaustive]
pub struct UpdateModification<'a> {
    pub new_state: Option<State<'a>>,
    pub related: Vec<RelatedContract>,
}

An update to a contract state or any required related contracts to update that state.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

new_state: Option<State<'a>>

related: Vec<RelatedContract>

Request an other contract so updates can be resolved.

Implementations

impl<'a> UpdateModification<'a>

pub fn valid(new_state: State<'a>) -> Self

Constructor for self when the state is valid.

pub fn unwrap_valid(self) -> State<'a>

Unwraps self returning a State.

Panics if self does not contain a state.

impl UpdateModification<'_>

pub fn requires(related: Vec<RelatedContract>) -> Result<Self, ContractError>

Constructor for self when this contract still is missing some RelatedContract to proceed with any verification or updates.

pub fn get_related(&self) -> &[RelatedContract]

Gets the pending related contracts.

pub fn into_owned(self) -> UpdateModification<'static>

Copies the data if not owned and returns an owned version of self.

pub fn requires_dependencies(&self) -> bool
