Struct ScriptTemplateUnlock 

pub struct ScriptTemplateUnlock { /* private fields */ }

Return type for template unlock methods.

Contains functions to sign a transaction input and estimate the unlocking script length.

Implementations

impl ScriptTemplateUnlock

pub fn new<S, E>(sign_fn: S, estimate_length_fn: E) -> Self

where S: Fn(&SigningContext<'_>) -> Result<UnlockingScript> + Send + Sync + 'static, E: Fn() -> usize + Send + Sync + 'static,

Creates a new ScriptTemplateUnlock.

Arguments

• sign_fn - A function that signs a transaction input
• estimate_length_fn - A function that estimates the unlocking script length

pub fn sign(&self, context: &SigningContext<'_>) -> Result<UnlockingScript>

Signs a transaction input to produce an unlocking script.

Arguments

• context - The signing context with transaction data

Returns

The unlocking script, or an error if signing fails.

pub fn estimate_length(&self) -> usize

Estimates the unlocking script length in bytes.

This is useful for fee estimation before the actual signature is created.

Trait Implementations

impl Debug for ScriptTemplateUnlock

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
