Why an argument vector was refused. Each variant names the offending token.

Variants

Unsupported

A recognised ROS flag nano-ros does not honour (see the module docs for the reason each one is refused).

Fields

flag: &'a str

The flag as written.

Unknown

A token inside a --ros-args scope that is not a ROS flag at all.

Fields

token: &'a str

The token as written.

MissingRule

-r/--remap was the last argument.

Fields

flag: &'a str

The flag as written.

InvalidRule

-r/--remap was followed by something that is not [node:]from:=to.

Fields

rule: &'a str

The rule as written.

IdentityRemap

A node-identity remap (__node, __name, __ns, or any __ rule).

Fields

rule: &'a str

The rule as written.

MissingValue

-p/--param or --params-file was the last argument.

Fields

flag: &'a str

The flag as written.

InvalidParam

-p/--param was followed by something that is not [node:]name:=value.

Fields

rule: &'a str

The rule as written.
