StorageCtx

tempo_precompiles::storage::thread_local

Struct StorageCtx

pub struct StorageCtx;

Expand description

Thread-local storage accessor that implements PrecompileStorageProvider without the trait bound.

This is the only type that exposes access to the thread-local STORAGE static.

§Important

Since it provides access to the current thread-local storage context, it MUST be used within a StorageCtx::enter closure.

§Sync with `PrecompileStorageProvider`

This type mirrors PrecompileStorageProvider methods but with split mutability:

Read operations (staticcall) take &self
Write operations take &mut self

Implementations§

impl StorageCtx

pub fn enter<S, R>(storage: &mut S, f: impl FnOnce() -> R) -> R
where S: PrecompileStorageProvider,

Enter storage context. All storage operations must happen within the closure.

§IMPORTANT

The caller must ensure that:

Only one enter call is active at a time, in the same thread.
If multiple storage providers are instantiated in parallel threads, they CANNOT point to the same storage addresses.

fn with_storage<F, R>(f: F) -> R
where F: FnOnce(&mut dyn PrecompileStorageProvider) -> R,

Execute an infallible function with access to the current thread-local storage provider.

§Panics

Panics if no storage context is set.

fn try_with_storage<F, R>(f: F) -> Result<R>
where F: FnOnce(&mut dyn PrecompileStorageProvider) -> Result<R>,

Execute a (fallible) function with access to the current thread-local storage provider.

pub fn with_account_info<T>( &self, address: Address, f: impl FnMut(&AccountInfo) -> Result<T>, ) -> Result<T>

Executes a closure with access to the account info, returning the closure’s result.

This is an ergonomic wrapper that flattens the Result, avoiding double ?.

pub fn chain_id(&self) -> u64

pub fn timestamp(&self) -> U256

pub fn beneficiary(&self) -> Address

pub fn set_code(&mut self, address: Address, code: Bytecode) -> Result<()>

pub fn sload(&self, address: Address, key: U256) -> Result<U256>

pub fn tload(&self, address: Address, key: U256) -> Result<U256>

pub fn sstore(&mut self, address: Address, key: U256, value: U256) -> Result<()>

pub fn tstore(&mut self, address: Address, key: U256, value: U256) -> Result<()>

pub fn emit_event(&mut self, address: Address, event: LogData) -> Result<()>

pub fn deduct_gas(&mut self, gas: u64) -> Result<()>

pub fn refund_gas(&mut self, gas: i64)

pub fn gas_used(&self) -> u64

pub fn gas_refunded(&self) -> i64

pub fn spec(&self) -> TempoHardfork

impl<'evm> StorageCtx

pub fn enter_evm<J, R>( journal: &'evm mut J, block_env: &'evm dyn Block, cfg: &CfgEnv<TempoHardfork>, f: impl FnOnce() -> R, ) -> R
where J: JournalTr<Database: Database> + Debug,

Generic entry point for EVM-like environments. Sets up the storage provider and executes a closure within that context.

pub fn enter_precompile<J, P, R>( journal: &'evm mut J, block_env: &'evm dyn Block, cfg: &CfgEnv<TempoHardfork>, f: impl FnOnce(P) -> R, ) -> R
where J: JournalTr<Database: Database> + Debug, P: Precompile + Default,

Entry point for a “canonical” precompile (with unique known address).

impl StorageCtx

fn as_hashmap(&self) -> &mut HashMapStorageProvider

Available on crate features test-utils only.

Returns a mutable reference to the underlying HashMapStorageProvider.

NOTE: takes a non-mutable reference because it’s internal. The mutability of the storage operation is determined by the public function.

Available on crate features test-utils only.

NOTE: assumes storage tests always use the HashMapStorageProvider
