pub struct AccountProcedureInfo { /* private fields */ }Expand description
Information about a procedure exposed in a public account interface.
The info included the MAST root of the procedure, the storage offset applied to all account storage-related accesses made by this procedure and the storage size allowed to be accessed by this procedure.
The offset is applied to any accesses made from within the procedure to the associated account’s storage. For example, if storage offset for a procedure is set to 1, a call to the account::get_item(storage_slot=4) made from this procedure would actually access storage slot with index 5.
The size is used to limit how many storage slots a given procedure can access in the associated account’s storage. For example, if storage size for a procedure is set to 3, the procedure will be bounded to access storage slots in the range [storage_offset, storage_offset + 3 - 1]. Furthermore storage_size = 0 indicates that a procedure does not need to access storage.
Implementations§
Source§impl AccountProcedureInfo
impl AccountProcedureInfo
Sourcepub const NUM_ELEMENTS_PER_PROC: usize = 8usize
pub const NUM_ELEMENTS_PER_PROC: usize = 8usize
The number of field elements needed to represent an AccountProcedureInfo in kernel memory.
Sourcepub fn new(
mast_root: Word,
storage_offset: u8,
storage_size: u8,
) -> Result<Self, AccountError>
pub fn new( mast_root: Word, storage_offset: u8, storage_size: u8, ) -> Result<Self, AccountError>
Returns a new instance of an AccountProcedureInfo.
§Errors
- If
storage_sizeis 0 andstorage_offsetis not 0. - If
storage_size + storage_offsetis greater thanMAX_NUM_STORAGE_SLOTS.
Sourcepub fn storage_offset(&self) -> u8
pub fn storage_offset(&self) -> u8
Returns the procedure’s storage offset.
Sourcepub fn storage_size(&self) -> u8
pub fn storage_size(&self) -> u8
Returns the procedure’s storage size.
