Enum Hypercall

#[non_exhaustive]
pub enum Hypercall<'a> {
    Cmdsize(&'a mut CmdsizeParams),
    Cmdval(&'a CmdvalParams),
    Exit(&'a ExitParams),
    FileClose(&'a mut CloseParams),
    FileLseek(&'a mut LseekParams),

}

Hypervisor calls available in Uhyve with their respective parameters. See the module level documentation on how to invoke them.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Cmdsize(&'a mut CmdsizeParams)

Get the size of the argument and environment strings. Used to allocate memory for Hypercall::Cmdval.

Cmdval(&'a CmdvalParams)

Copy the argument and environment strings into the VM. Usually preceeeded by Hypercall::Cmdsize so that the guest can allocate the memory for this call.

Exit(&'a ExitParams)

Exit the VM and return a status.

FileClose(&'a mut CloseParams)

FileLseek(&'a mut LseekParams)

FileOpen(&'a mut OpenParams)

FileRead(&'a mut ReadParams)

FileWrite(&'a WriteParams)

FileUnlink(&'a mut UnlinkParams)

SerialWriteByte(u8)

Write a char to the terminal.

SerialWriteBuffer(&'a SerialWriteBufferParams)

Write a buffer to the terminal.
