Expand description

Various settings that could be used to guide Marine how to load a module in a proper way.

Fields

mem_pages_count: Option<u32>

Maximum memory size accessible by a module in Wasm pages (64 Kb).

max_heap_size: Option<u64>

Maximum memory size for heap of Wasm module in bytes, if it set, mem_pages_count ignored.

logger_enabled: bool

Defines whether FaaS should provide a special host log_utf8_string function for this module.

host_imports: HashMap<String, HostImportDescriptor>

Export from host functions that will be accessible on the Wasm side by provided name.

wasi: Option<FaaSWASIConfig>

A WASI config.

logging_mask: i32

Mask used to filter logs, for details see log_utf8_string
