impl<'a, 'b> Environment<'a, 'b>

pub fn new(
    global_context: &'a mut GlobalContext<'b>,
    contract_context: &'a ContractContext,
    call_stack: &'a mut CallStack,

pub fn nest_as_principal<'c>(&'c mut self, sender: Value) -> Environment<'c, 'b>

pub fn nest_with_caller<'c>(&'c mut self, caller: Value) -> Environment<'c, 'b>

pub fn eval_read_only(
    &mut self,
    contract_identifier: &QualifiedContractIdentifier,
    program: &str
) -> Result<Value>

pub fn eval_raw(&mut self, program: &str) -> Result<Value>

pub fn run_free<F, A>(&mut self, to_run: F) -> A where
    F: FnOnce(&mut Environment<'_, '_>) -> A, 

Used only for contract-call! cost short-circuiting. Once the short-circuited cost has been evaluated and assessed, the contract-call! itself is executed “for free”.

pub fn execute_contract(
    &mut self,
    contract_identifier: &QualifiedContractIdentifier,

pub fn stx_transfer(
    &mut self,
    from: &PrincipalData,
    to: &PrincipalData,
    amount: u128
) -> Result<Value>

Top-level STX-transfer, invoked by TokenTransfer transactions. Only commits if the inner stx_transfer_consolidated() returns an (ok true) value. Rolls back if it returns an (err ..) value, or if the method itself fails for some reason (miners should never build blocks that spend non-existent STX in a top-level token-transfer)

impl CostTracker for Environment<'_, '_>

fn compute_cost(

) -> Result<ExecutionCost, CostErrors>

fn add_cost(&mut self, cost: ExecutionCost) -> Result<(), CostErrors>

fn short_circuit_contract_call(
    &mut self,
    contract: &QualifiedContractIdentifier,
    function: &ClarityName,
    input: &[u64]
) -> Result<bool, CostErrors>

Check if the given contract-call should be short-circuited. If so: this charges the cost to the CostTracker, and return true If not: return false
