Struct Template 

#[non_exhaustive]
pub struct Template {
    pub name: String,
    pub module_name: String,
    pub package_id: String,
    pub package_name: String,
    pub fields: Vec<Field>,
    pub choices: Vec<Choice>,
    pub key: Option<DamlType>,
}

A template: its payload fields, its choices, and an optional contract key.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

name: String

The template name (PascalCase) — also the Rust payload struct name.

module_name: String

The Daml module the template is defined in, dotted (e.g. Splice.Amulet). Part of the on-ledger template id.

package_id: String

The id (hash) of the package the template is defined in. Pins the exact template version in an on-ledger template id.

package_name: String

The Daml package name (e.g. splice-amulet), used for the upgrade-friendly #<package-name> template-id form so the participant resolves the vetted version under Smart Contract Upgrade.

fields: Vec<Field>

The payload fields, in declaration order.

choices: Vec<Choice>

The choices exercisable on a contract of this template.

key: Option<DamlType>

The contract key type, if the template declares a key.

Implementations

impl Template

pub fn new( name: impl Into<String>, module_name: impl Into<String>, package_id: impl Into<String>, package_name: impl Into<String>, ) -> Self

A template with its on-ledger identity, and no fields, choices or key yet.

Trait Implementations

impl Clone for Template

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Template

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

Formats the value using the given formatter.

impl Eq for Template

impl PartialEq for Template

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
