Function add_tx

pub fn add_tx(
    tx: &Transaction,
    tx_blob: &Vec<u8>,
    tx_hash: &TxHash,
    block_height: &BlockHeight,
    tables: &mut impl TablesMut,
) -> Result<TxId, RuntimeError>

Add a Transaction (and related data) to the database.

The block_height is the block that this tx belongs to.

Note that the caller’s input is trusted implicitly and no checks are done (in this function) whether the block_height is correct or not.

⚠️ 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

Notes

This function is different from other sub-functions and slightly more similar to add_block() in that it calls other sub-functions.

This function calls:

• add_output()
• add_rct_output()
• add_key_image()

Thus, after add_tx, those values (outputs and key images) will be added to database tables as well.

Panics

This function will panic if:

• block.height > u32::MAX (not normally possible)

Errors

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