Struct InstallSpec 

#[non_exhaustive]
pub struct InstallSpec {
    pub wasm: Vec<u8>,
    pub init_bytes: Vec<u8>,
    pub cycles: u128,
    pub install_sender: Option<Principal>,
    pub label: Option<String>,
}

Inputs and diagnostic context for one generic canister installation.

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.

wasm: Vec<u8>

Wasm module installed into the newly created canister.

init_bytes: Vec<u8>

Raw Candid or application-specific initialization bytes.

cycles: u128

Extra cycles added after PocketIC creates the canister and before install.

install_sender: Option<Principal>

Optional sender for the management-canister install operation.

label: Option<String>

Optional human-readable context included in install errors.

Implementations

impl InstallSpec

pub const fn new(wasm: Vec<u8>, init_bytes: Vec<u8>, cycles: u128) -> Self

Build one generic canister install specification.

pub const fn install_sender(self, sender: Principal) -> Self

Set the management-call sender used for install_canister.

pub fn label(self, label: impl Into<String>) -> Self

Set a diagnostic label for install failures.
