Struct Capabilities 

pub struct Capabilities {
    pub filesystem: Option<FilesystemCap>,
    pub http: Option<HttpCap>,
    pub sockets: Option<SocketsCap>,
    pub other: BTreeMap<String, Value>,
}

Capability declarations from the std:capabilities map in act:component.

Well-known capabilities have typed fields. Unknown third-party capabilities are collected in other. Serializes as a CBOR/JSON map keyed by capability ID.

Fields

filesystem: Option<FilesystemCap>

wasi:filesystem — filesystem access.

http: Option<HttpCap>

wasi:http — outbound HTTP requests.

sockets: Option<SocketsCap>

wasi:sockets — outbound TCP/UDP connections.

other: BTreeMap<String, Value>

Third-party capabilities keyed by identifier.

Implementations

impl Capabilities

pub fn is_empty(&self) -> bool

True if no capabilities are declared.

pub fn has(&self, id: &str) -> bool

Check if a capability is declared by its string identifier.

pub fn fs_mount_root(&self) -> Option<&str>

Get the mount-root parameter from the wasi:filesystem capability.
