fn from_ext<E: Extension>(e: &E) -> Self

Compute the type of an extension Extensions are always leaf, they should have a fixed type property and hence should not fail

Provided Methods

fn sanity_checks(&self)

Any extra sanity checks/assertions that should be applied after typechecking

fn from_sha256() -> Self

Type property of a Sha256 hash. Default implementation simply passes through to from_hash

fn from_hash256() -> Self

Type property of a Hash256 hash. Default implementation simply passes through to from_hash

fn from_ripemd160() -> Self

Type property of a Ripemd160 hash. Default implementation simply passes through to from_hash

fn from_hash160() -> Self

Type property of a Hash160 hash. Default implementation simply passes through to from_hash

fn from_after(t: LockTime) -> Self

Type property of an absolute timelock. Default implementation simply passes through to from_time

fn from_older(t: Sequence) -> Self

Type property of a relative timelock. Default implementation simply passes through to from_time

fn cast_true(self) -> Result<Self, ErrorKind>

Cast by changing [X] to AndV([X], True)

fn cast_unlikely(self) -> Result<Self, ErrorKind>

Cast by changing [X] to or_i([X], 0). Default implementation simply passes through to cast_or_i_false

fn and_n(left: Self, right: Self) -> Result<Self, ErrorKind>

Computes the type of an AndN fragment

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
