Struct NfcEffects 

pub struct NfcEffects<'a, 'b, S: AppState> { /* private fields */ }

Convenience builder for standard NFC host capabilities.

Implementations

impl<'a, 'b, S: AppState> NfcEffects<'a, 'b, S>

pub fn availability(self) -> EffectBuilder<'a, 'b, S>

Queries whether NFC is supported, enabled, and which NFC modes are available.

Use this before showing scan/write controls so the UI can distinguish a missing NFC chip from a disabled adapter or unsupported operation.

pub fn scan_tag(self, request: NfcScanRequest) -> EffectBuilder<'a, 'b, S>

Starts a one-shot NFC scan session.

request declares allowed technologies, optional user-facing prompt text, timeout, and whether multiple records should be collected. The success action receives an NfcTag when the host reads a compatible tag.

pub fn write_tag(self, request: NfcWriteRequest) -> EffectBuilder<'a, 'b, S>

Starts an NFC tag write session.

request.records contains the portable NDEF-like records to write. Hosts may require the user to tap a writable tag after the operation starts and may reject read-only or incompatible tags.

pub fn emulate_tag( self, request: NfcEmulationRequest, ) -> EffectBuilder<'a, 'b, S>

Requests host NFC card emulation for the supplied records.

Use this only on platforms and devices that support card emulation for the product scenario. Many hosts support scanning but not emulation.

pub fn cancel_session(self) -> EffectBuilder<'a, 'b, S>

Cancels the active NFC session, if one is running.

Use this when the user dismisses the screen that started scanning, writing, or emulation. Hosts may return success when no session is active.
