Module imports

Conveniently groups all framework imports required by a smart contract form the framework.

Re-exports

• pub use crate::abi::TypeAbi;
• pub use crate::api::ErrorApiImpl;
• pub use crate::api::ManagedTypeApi;
• pub use crate::api::VMApi;
• pub use crate::contract_base::ContractBase;
• pub use crate::contract_base::ProxyObjBase;
• pub use crate::contract_base::ProxyObjNew;
• pub use crate::err_msg;

Macros

• non_zero_usize
  Converts usize to NonZeroUsize or returns SCError.
• require
  Allows us to write Solidity style require!(<condition>, <error_msg>) and avoid if statements.
• sc_format
• sc_panic
• sc_print

Structs

• ArrayVec
  A vector with a fixed capacity.
• DecodeError
• ESDTSystemSCProxy
  Proxy for the ESDT system smart contract.
• ESDTSystemSCProxyMethods
  Method container of the ESDT system smart contract proxy.
• ESDTSystemSmartContractProxyDeprecated
  Proxy for the ESDT system smart contract. Unlike other contract proxies, this one has a fixed address, so the proxy object doesn’t really contain any data, it is more of a placeholder.
• Empty
  Empty structure with an empty bytes representation. Equivalent to false, 0 or [u8; 0], but more explicit.
• FungibleTokenProperties
• IgnoreValue
  Structure that allows taking a variable number of arguments, but does nothing with them, not even deserialization.
• MetaTokenProperties
• MultiValue2
• MultiValue3
• MultiValue4
• MultiValue5
• MultiValue6
• MultiValue7
• MultiValue8
• MultiValue9
• MultiValue10
• MultiValue11
• MultiValue12
• MultiValue13
• MultiValue14
• MultiValue15
• MultiValue16
• MultiValueVec
  Structure that allows taking a variable number of arguments or returning a variable number of results in a smart contract endpoint.
• NonFungibleTokenProperties
• PlaceholderInput
  Temporary value used for any kind of templates.
• PlaceholderOutput
  Temporary value used for any kind of templates.
• SemiFungibleTokenProperties
• TokenProperties
• TokenPropertyArguments
  Represents property arguments to be sent to the system SC.
• UserBuiltinProxy
  Proxy describing the user builtin function signatures.
• UserBuiltinProxyMethods

Enums

• OptionalValue
  A smart contract argument or result that can be missing.

Traits

• Add
  The addition operator +.
• AddAssign
  The addition assignment operator +=.
• BitAnd
  The bitwise AND operator &.
• BitAndAssign
  The bitwise AND assignment operator &=.
• BitOr
  The bitwise OR operator |.
• BitOrAssign
  The bitwise OR assignment operator |=.
• BitXor
  The bitwise XOR operator ^.
• BitXorAssign
  The bitwise XOR assignment operator ^=.
• Div
  The division operator /.
• DivAssign
  The division assignment operator /=.
• IntoMultiValue
  Defines conversion of a type to its multi-value representation.
• Mul
  The multiplication operator *.
• MulAssign
  The multiplication assignment operator *=.
• NestedDecode
  Trait that allows zero-copy read of value-references from slices in LE format.
• NestedEncode
  Trait that allows zero-copy write of value-references to slices in LE format.
• Rem
  The remainder operator %.
• RemAssign
  The remainder assignment operator %=.
• Shl
  The left shift operator <<. Note that because this trait is implemented for all integer types with multiple right-hand-side types, Rust’s type checker has special handling for _ << _, setting the result type for integer operations to the type of the left-hand-side operand. This means that though a << b and a.shl(b) are one and the same from an evaluation standpoint, they are different when it comes to type inference.
• ShlAssign
  The left shift assignment operator <<=.
• Shr
  The right shift operator >>. Note that because this trait is implemented for all integer types with multiple right-hand-side types, Rust’s type checker has special handling for _ >> _, setting the result type for integer operations to the type of the left-hand-side operand. This means that though a >> b and a.shr(b) are one and the same from an evaluation standpoint, they are different when it comes to type inference.
• ShrAssign
  The right shift assignment operator >>=.
• Sub
  The subtraction operator -.
• SubAssign
  The subtraction assignment operator -=.
• TopDecode
  Trait that allows zero-copy read of values from an underlying API in big endian format.
• TopEncode

Type Aliases

• IssueCall
  The specific Tx type produces by the issue operations of the ESDTSystemSCProxy.
