Function add_rct_output 

Source 
pub fn add_rct_output(
    rct_output: &RctOutput,
    table_rct_outputs: &mut impl DatabaseRw<RctOutputs>,
) -> DbResult<AmountIndex>
Expand description

Add an RctOutput to the database.

Upon Ok, this function returns the AmountIndex that can be used to lookup the RctOutput in get_rct_output().

§⚠️ Invariant ⚠️

This function mainly exists to be used internally by the parent function crate::ops::block::add_block.

add_block() makes sure all data related to the input is mutated, while this function does not, it specifically mutates particular tables.

This is usually undesired - although this function is still available to call directly.

When calling this function, ensure that either:

  1. This effect (incomplete database mutation) is what is desired, or that…
  2. …the other tables will also be mutated to a correct state

§Errors

This function returns cuprate_database::RuntimeError::KeyNotFound if the input (if applicable) doesn’t exist or other RuntimeError’s on database errors.
