The actor interface defines how ailets interact with their environment. Each ailet is an actor that receives input through streams and produces output through streams.
get_name
Name of the actor.
open_read
int open_read(const char *param_name, unsigned int idx);
Open the idxth stream associated with the parameter param_name.
Return a file descriptor on success, or -1 on error. In case of error, errno is set.
open_write
int open_write(const char *param_name);
Open a write stream associated with the parameter param_name.
Return a file descriptor on success, or -1 on error. In case of error, errno is set.
read
int read(int fd, voif buffer[count], int count)
Read up to count bytes from the file descriptor fd into the buffer.
Return the number of bytes read. If the end of the file is encountered, 0 is returned. On error, -1 is returned, and errno is set appropriately.
write
int write(int fd, const void buffer[count], int count);
Writes up to count bytes from the buffer to the file descriptor fd.
Return the number of bytes written, which might be less than count. On error, return -1 and sets errno appropriately.
The following file descriptors are predefined:
STDOUT_FILENO = 1 (Standard output)STDERR_FILENO = 2 (Standard error; conventionally used for logging)METRICS_FD = 3 (Metrics output stream)TRACE_FD = 4 (Traces output stream)close
int close(int fd);
Close the file descriptor fd.
get_next_name
char *get_next_name(const char *base_name);
Return an unique name with the prefix base_name.
get_errno
int get_errno(void);
As seen in POSIX.
Based on the experience developing a tool for gpt4o, the following functions were sufficient:
add_value_node(value: bytes, explain: Optional[str]): Creates a new value node.
instantiate_with_deps(target: str, aliases: dict[str, str]): Creates a new instance of a plugin (either a tool or a model).
alias(alias: str, node_name: Optional[str]): Creates or updates an alias pointing to a node.
detach_from_alias(alias: str): Freezes the dependencies of nodes associated with the alias, preventing them from being affected by subsequent changes to the alias.
