Expand description

All ocall definitions for pink Sidevm.

Required Methods

Close given resource by id.

Poll given resource by id and return a dynamic sized data.

Poll given resource to read data. Low level support for AsyncRead.

Poll given resource to write data. Low level support for AsyncWrite.

Shutdown a socket

Poll given resource to generate a new resource id.

Mark a task as ready for next polling

Get the next waken up task id.

Enable logging for ocalls

Get awake wakers

Get random number

Create a timer given a duration of time in milliseconds.

Send data to a oneshot channel.

Percentage of the gas remaining to the next breath

Create a TCP socket, bind to given address and listen to incoming connections.

If tls_config is not None, then the socket will be TLS encrypted. Invoke tcp_accept on the returned resource_id to accept incoming connections.

Accept incoming TCP connections.

Accept incoming TCP connections without returning the remote address.

Initiate a TCP connection to a remote endpoint.

Initiate a TLS/TCP connection to a remote endpoint.

Print log message.

Get value from the local cache.

Set value to the local cache.

Set expiration time for a key in the local cache.

Remove a value from the local cache.

Returns the previous value if it existed.

Create input channel
