Struct McpArguments 

pub struct McpArguments { /* private fields */ }

Owning decoder for MCP tool argument objects.

Generated form and table integrations consume arguments through this type instead of open-coding JSON map removal. Manual tool integrations can use the same helpers and call McpArguments::finish when every expected argument has been consumed.

Implementations

impl McpArguments

pub fn new(arguments: McpToolArguments) -> Self

Creates an owning decoder from normalized MCP arguments.

pub fn is_empty(&self) -> bool

Returns whether any arguments remain unconsumed.

pub fn as_inner(&self) -> &McpToolArguments

Returns the remaining raw argument object.

pub fn into_inner(self) -> McpToolArguments

Returns the remaining raw argument object.

pub fn take_raw(&mut self, field: &str) -> Option<Value>

Removes and returns one raw argument by wire field name.

pub fn take_raw_one_of( &mut self, field: &str, aliases: &[&str], ) -> Result<Option<Value>, McpToolError>

Removes and returns one raw argument by canonical field name or alias.

Errors

Returns McpToolError::DuplicateField when both the canonical field name and an alias are present, or multiple aliases are present.

pub fn take_required_tool_value<T>( &mut self, field: impl Into<String>, ) -> Result<T, McpToolError>

where T: McpToolValue,

Removes, requires, and decodes one typed argument by field name.

Errors

Returns McpToolError when the field is missing or when T rejects the raw JSON value.

pub fn take_required_tool_value_from<T>( &mut self, field: &'static str, aliases: &'static [&'static str], ) -> Result<T, McpToolError>

where T: McpToolValue,

Removes, requires, and decodes one typed argument by field name or alias.

Errors

Returns McpToolError when no accepted field name is present, duplicate field spellings are present, or T rejects the raw JSON value.

pub fn take_present_tool_value<T>( &mut self, field: impl Into<String>, ) -> Result<Option<T>, McpToolError>

where T: McpToolValue,

Removes and decodes an optional typed argument by field name.

Errors

Returns McpToolError when T rejects the raw JSON value.

pub fn take_present_tool_value_from<T>( &mut self, field: &'static str, aliases: &'static [&'static str], ) -> Result<Option<T>, McpToolError>

where T: McpToolValue,

Removes and decodes an optional typed argument by field name or alias.

Errors

Returns McpToolError when duplicate field spellings are present or T rejects the raw JSON value.

pub fn finish(self) -> Result<(), McpToolError>

Verifies that no unrecognized arguments remain.

Errors

Returns McpToolError::UnknownField when any raw arguments remain.
